The Electric Current
When a conductor joins two points of different potential, electricity flows
from one to the other along the conductors until the potentials are equal.
This process is very rapid, and with good conductors is completed in a
fraction of a second. While it lasts, an electric current is said to flow
from one point to the other. By convention, the direction of the current is
said to be that from the higher to the lower potential, i.e. the direction
in which positive charges would travel, but actually, owing to their much
greater mobility, it is the negative electrons which move, and it is their
motion which constitutes the current.

Faraday's Experiment
Faraday knew from his long study of electricity that magnetism should be
able to produce a current, as well as vice versa. In spite of his various
failures, the idea of producing a current directly by magnetic action
remained firm in his thoughts. One of his friends said later how at this
period of his long life Faraday used to carry about with him in his pocket
a small rough model of electro-magnetic apparatus. This consisted simply of
an inch-long straight iron core with some turns of copper wire wound round
it. The basic idea he had in mind was this: if an electric current in a
wire can produce a magnetic effect, why should not a magnet near a
conducting wire produce an electric current?

The Discovery of Magnetic Induction.
The discovery in 1820 that there was a close connection between electricity
and magnetism was very exciting -until then, the two subjects had been
considered as quite independent. The first discovery was that currents in
wires make magnetic fields; then in the same year, it was found that wires
carrying current in a magnetic field have forces on them. In 1840 Faraday
discovered - electric effects exist only when there is something changing.
If one of a pair of wires has a carrying current, a current is induced in
the other, or if a magnet is moved near an electric circuit, there is a
current. We say that currents are induced.

Generating an Electric Current
Alessandro Volta, a professor of physics, established the true source of
the electric current. He demonstrated that it could be produced by the
action of dissimilar metals. In 1800 he developed the first electric
battery, a device known as a voltaic pile. Although he tried a number of
different materials he found that the best results were obtained when he
used silver and zinc as the two metals. The pile consisted of a series of
small disks of these and of cardboard, the latter having been soaked in a
salt solution.

Uzbekistan Chooses Its Way.
The proclamation of Independence on September 1-st 1991 was landmark
in the history of the Republic. Uzbekistan is a multi-national country
inhabited by more than 130 nations and nationalities.
Uzbekistan's present day economy is diversified consisting of
agricultural and manufacturing industries including the gas and oil
industries, ferrous and nonferrous metallurgy, coal and uranium fields,
engineering, cotton-ginning, textiles, canning and others. Uzbekistan
possesses the largest economic potential and highest growth figures amongst
the republics of Central Asia in both industrial and agricultural
development. An important place in the Republic of Uzbekistan's economy is
given to the rural sectors and especially the cotton growing industry.
Uzbekistan ranks 4th in the world's gross cotton yield stakes. The
substantial scientific-technical potential, both in the industrial and
agricultural development sectors, has been created in the Republic.
Uzbekistan maintains foreign trade connections with many countries in the
world, participates in various international exhibitions and festivals,
enjoys the memberships of many international organizations, banks and
funds. At present over 120 countries of the world have recognized the
Republic of Uzbekistan and diplomatic relations have been established with
more than 60 of them. In Tashkent - the capital of independent Uzbekistan -
there are 27 embassies, a UN mission and the opening of a further number of
embassies is planned. Broad opportunities have been opened up for the
involvement of the Republic in an international division of labour and for
the extension of foreign trade, ties having been obtained through
independence and sovereignty. Uzbekistan today has a developed
infrastructure. The total length of railroads is over 3.5 thousand
kilometers, connecting all the large economic centres of the Republic,
ensuring entry to the CIS and other countries. There are over 40 thousand
kilometers of highway. Uzbekistan is a Republic where traditions and
principles of world community are highly honoured and being a full member,
the Republic concentrates its efforts on the elaboration and realization of
independent economic and social policies directed at renewing life, the
intensive development of the national economy, the improvement of the
peoples' well-being and its rapid integration into the world economic
structure. The peoples of Uzbekistan look ahead with optimism.
Tashkent.
The early information about our city you can find in ancient Eastern
annals of the 2 century- BC. Caravans going by the Great Silk Road passed
Chach (the ancient name of Tashkent). Convenient geographical position
favoured the city in its turning into the capital of the state.
At the end of the 10-th and the beginning of the 12-th century people
more often called Chach by another name - Tashkent, which means "Settlement
made of stone".
The monuments of medieval architecture harmonize with the modern
architectural constructions. This combination differentiates Tashkent from
many other cities. So does the hospitality, cordiality of Uzbek people.
Tashkent always welcomes guests. International meetings, symposiums,
conferences, festivals are held here. The city has many friends-sister
cities; Karachi,
Seattle, Tunis, Patiala, Birmingham. That's why Tashkent is considered to
be "the city of
friendship and brotherhood".
Today Tashkent - is the, capital of Uzbekistan, cultural center of the
country. There are 9 theatres, Conservatory, museums, such as Art Museum,
Museum of history of Uzbekistan. Tashkent has shady parks with queen
fountains, concert, art exhibition halls, stadiums, swimming pools,
libraries, gardens.
Opera and Ballet theatre named after Navoi looks like the palace from
the outside. The palace where music reigns. Plays are on here almost every
evening. And during a year the theatre presents 2-3 premiers at spectators'
disposal. The building was constructed in 1947. The figures of Uzbek
traditional monumental architecture are used in the facade decoration.
Exhibits in the exhibition hall of Uzbekistan Artists Union change
continually. Light, roomy halls are put not only at famous artists
disposal, but that of youths as well. There is an exhibition hall in the
centre of the city. It was opened in 1974.
While making a city tour in Tashkent, you cannot help paying attention
at the peculiarities of modern buildings. Each of them is the part of the
national culture. The facades of buildings are decorated with the elements
of national ornament. Architects try to take into account the national
traditions. For example, one of the blocks was built in a way neighbours
can easily contact with each other, using special galleries. Builders
create modern blocks trying to be close to the feel of makhalla
(community). The modern construction - TV tower is not standard. It is the
highest construction in Central Asia. And it is adjusted to the seismicity
9. Its height - 375 meters. On the height of 100 meter? and 220 metersthe
tower is girdled with telecasting station for 5 programs, broadcasting
station, meteorological station. There is also observation site, where you
can enjoy the magnificent view of the city, revealing bars and restaurant
here. At the restaurants you will be served with the dishes of Uzbek
cuisine. The interior is decorated with national paintings.
Tashkent is the only city in Central Asia, which has underground. The
construction of it started in 1973 and in 1977 the first line began to
operate. Tashkent Underground - it is 30 stations and they differ from each
other. Architectural and artistic decoration of station depicts its name.
The leading architects and artists of Uzbekistan took part in designing of
the stations. Underground is a favourite means of transport of people in
Tashkent. You can go to any part of the city in no time (The interval
between trains is 240 seconds ).
Great Britain.
The United Kingdom of Great Britain and Northern Ireland- this is the
official name of Great Britain. It is composed of the island of Great
Britain, the northeastern part of Ireland and multitude of small islands.
Great Britain separated from the European continent by the North Sea and
the English Channel. In the west the Atlantic Ocean and the Irish Sea wash
Great Britain.
The Atlantic Ocean and the seas washing Great Britain as well as the
south western winds affect the climate of the country making it maritime
and damp.
The North and West of G. B. are mountainous. The Pennines located in
the central part of the island of G. B. stretch from north to south. Many
short rivers flow down the Pennines.
Northern Ireland presents a hilly extremity of the Central Plain.
The United Kingdom comprises England and Wales, which occupy the
greater part of the island of G. B., Scotland in the North of G. B., and
Northern Ireland situated in the north-east of Ireland.
The principal part of G. B. is England. Northern Ireland enjoys the
rights 0f an autonomous region. The territory of G. B. is divided into
counties - Lancashire, Yorkshire, etc.
The English nation arose as a result of the amalgamation of the native
population of the British Isles-Celts with the Germanic tribes of angles
and Saxons who repeatedly invaded Britain, and with the Normans who lived
in the North of France and conguered Britain in the middle of the 11-th
century. The present descendants of the Celts - Scotchmen, Welsmen and
Irishmen constitute less than one fifth of the total population of the
country.
The population of G. B. speaks English.
G. B. is a country of highly developed culture. The eminent physicist
Newton, the famous naturalist Darwin greatly contributed to science, while
the works of great master of tragedy Shakespeare, the poet Byron and the
novelist Dickens enriched world literature and art.
G. B. is a highly developed industrial country. Coal-mining,
metallurgical, textile, shipbuilding, electrical engineering, automobile,
aircraft and chemical industries are of great importance for Britain.
G. B. - is a constitutional monarchy. The head of the state is the
king or the queen who ascend the throne by right of succession. The
Englishmen say of their monarchs: "They reign, but don't rule. "
The monarch's power is limited by the Parliament consisting of two
Chambers: the Chamber of Commons and the Chamber of Lords.
The Chamber of Commons is popularly elected and the Chamber of Lords
is composed of high-born nobility who hold their title by right of
succession.
The executive power is welded by the Cabinet presided by the Prime
Minister. The post of the Premier is filled by the leader of the party
which holds the majority in the Chamber of Commons.
There are two major parties in G. B. - the Conservative and the
Labour.
The National Programme Of Personnel Training.
The National Programme of Personnel Training corresponds to provisions
of the Decree of the Republic of Uzbekistan “On Education”, elaborated on
the basis of the analysis of national experience, proceeding from the world
achievements in the system of education and oriented on molding of new
staff generation with high common and professional culture, creative and
social activity, ability to orientate itself independently in socio-
political life, capable to put forward and solve perspective tasks.
The aim of the present programme is the fundamental reforming of
education system, elaboration of the national education system for training
of highly qualified personnel up to the level advance democratic states and
meeting the requirements of high spirit and morals.
The implementation of the aim demands the development of mutually
beneficial international collaboration in personnel training.
The international legal base for cooperation in for personnel training
is created, prior directions of international cooperation are being
realized, international education structures are developed, exchange of
scientific researches and teaching staff and students are widened. The base
for international recognition of national decree on education is prepared.
The activity of concerned Ministries and Departments, Embassies of
Uzbekistan for the sake of intensive attraction the direct and indirect
foreign investments for specialists training is intensified.
Revival of spiritual values and national self-consciousness.
No society can see its perspective without the development and
strengthening its spiritual potential, spiritual and moral values in
consciousness of people.
The cultural values of the nation, its spiritual heritage have been a
powerful source of spirituality for the peoples of the East during
millennia. In spite of rigid ideological pressure during a long period, the
people of Uzbekistan have managed to preserve their historical and cultural
values and their local traditions, that were carefully transferred from
generation to generation.
From the first days of our independence, the major problem, raised on
state policy level has been to revive that huge, invaluable spiritual and
cultural legacy that was formed by our ancestors during many centuries.
But we were aware that the simple deny of values of the former system
posed a danger of political and cultural extremism which did not imply any
creative programme. At the same time, spontaneous and thoughtless return to
the values, traditions and tenor of the past can lead to another extreme:
to the denial of modern life, to the denial of the necessity to modernize
the society.
Historical memory, restoration of an objective and truthful history of
the nation, native territory, territory of the state is given an extremely
important place in the revival and growth of national self-consciousness,
and if you agree also the national pride.
Historical experience, succession of traditions - all this should
become those values, on which new generations are brought up.
Static Electricity.
We shall give an account of the electrification of bodies in terms of
atomic structure. The atoms, normally containing equal numbers of electrons
and protons (units of negative and positive charges respectively), are
broken up, and electrons pass from one body to another, leaving the former
positively and the later negatively charged. This is not the normal
condition of matter, and at the first opportunity the positively charged
body acquires electrons and the negatively charged body expels electrons,
so as to recover the neutral state.
The Electric Current.
When a conductor joins two points of different potential, electricity
flows from one to the other along the conductor until the potentials are
equal.
This process is very rapid, and with good conductors is completed in a
fraction of a second. While it lasts, an electric current is said to flow
from one point to the other. By convention, the direction of the current is
said to be that from the higher to the lower potential, i. e. the direction
in which positive charges would travel, but actually, owing to their much
greater mobility, it is the negative electrons, which move, and it is their
motion, which constitutes the current. It is unfortunate that, before the
existence of electrons was thought of the conventional direction of the
current should have been wrongly chosen, but it is now too late to alter
the convention. The student must bear in mind that when a current is said
to flow from A to B, what actually happens is that electrons flow from B to
A.
Magnetism.
The existence of magnets shows that matter can be active. Everyone
knows something of the property of certain pieces of iron steel - and to a
smaller extent, cobalt and nickel- by which they can attract other pieces
of iron and steel and hold them up against gravity; and there is, in fact,
a naturally occurring oxide of iron, knows as "lodestone" which has the
same property. If we suspend a magnet by its center so that it hangs
horizontally, and then bring the end of another magnet near one of its
ends, we find that the suspended magnet is either attracted or repelled;
while if we present the other end of the second magnet to the same end of
suspended one, the reverse happens-there is either repulsion or attraction.
On the other hand, either end of the magnet will attract pieces of iron,
which are not magnets.
Magnetic Polarity.
We have here a behavior somewhat similar to that of electrified. The
magnitude of the force is again far greater than that of gravity; and there
is the same attraction and repulsion between bodies affected, and only
attraction between an affected and an unaffected body. We therefore speak
of positive and negative magnetization if we wish. We do not, however, use
these terms, but speak of two ends of the magnet as "north" and "south"
poles. The reason for this is that a freely suspended magnet always hangs
so that one end points approximately towards the north and the other
approximately towards the south, and if we disturb it, it always returns to
the position. We therefore speak of the north-speaking poles, and these
names are usually abbreviated to north (N) and south (S) poles.
Conductors And Non-Conductors.
The ease with which this is done depends on the atomic constitution of
the body. In some substances electrons move fairly easily, while in others
they find movement difficult. This difference is expressed by what is
called the electrical conductivity of the body. Substances through which
electrons move easily are called good conductors. Generally speaking, among
solids metals are good conductors and non-metals are poor conductors. If
materials are arranged in the order of their conductivity it is found
although there is no sudden transition from a group of very good to a group
of very bad conductors, the atoms are restored to their normal state as
fast as they are broken up, by the passage of electrons from the rod to the
Earth to the rod, as the case may require. (The Earth must be regarded as
containing free electrons and as being able to accommodate many more,
without, observably electrified, owing to its great size. Any electrified
body, whether charged positively or negatively, immediately becomes neutral
when connected with the Earth either directly or through a conductor. ) It
appears to be always the electrons that move, and not the positively
charged atoms (or 'ions', as they are called). This would be expected,
because of the much smaller mass of the electrons. If, however, a conductor
be held by an insulating handle, so that electrons cannot pass between it
and the hand. It also can be electrified by friction. In all experiments on
frictional electricity the apparatus used must be quite dry, otherwise any
electrification produced is destroyed, since moisture has conducting
properties.
Permanent Magnetism.
The electric current consists simply of electrons or ions traveling
round and round a circuit, and it may well be asked why, apart from the
general thirst for knowledge, we should be interested to constructing vast
machines in order to make invisible particles do the same thing over and
over again. Two reasons have already been given: we can use such a process
to produce chemical action, as in electrolysis and electroplating, and we
can use it to produce light and heat. The third, and the most important
reason of all, is that we can use it to produce magnetic force. It has
already been said that a circular current acts as a magnet, but before
considering the magnetic effects of a current in more detail we must
examine the properties of the so-called "permanent" magnets - pieces of
iron and steel which attract other pieces of iron and steel without any
obvious connection with electricity at all, although, as already stated, we
believe the force to be associated with the motion of electrons within the
magnets.
Interpretation Of Magnetism.
We assume that an electron moving in an orbit is a small magnet. For
simplicity, suppose the orbit is a circle in plane of this sheet of paper,
and suppose the electron is revolving in a clockwise direction. Then the
upper side of the paper is a S-pole and the lower side is a N-pole. If
another similar orbit existed in a parallel plane just above the first,
there would therefore be attraction between them and the orbits would
approach one another, while if the second electrons were revolving in the
opposite direction to the polarity they would be reversed and there would
be repulsion. Each atomic electron revolving in its orbit is therefore a
small magnet, and the magnetic properties of observable bodies must be
expressed in terms of interaction of these intra-atomic magnets. Like the
assumption of the existence of elementary particles in atoms, this is not
orbitrary guesswork. We can experiment with electrically charged bodies of
observable size moving in orbits, and we can find that they do in fact
behave as magnets in the manner just described. It is therefore quite
reasonable to suppose that the elementary charges behave similarly, and
provide us with elements out of which we can build a satisfactory theory of
magnetism.
