Слайд 2 In 1911, the Dutch physicist Kamerling-Onnes found that

In 1911, the Dutch physicist Kamerling-Onnes found that when the mercury

when the mercury in liquid helium is cooled, the

resistance first varies gradually

Superconductivity is the property of some materials to have a strictly zero electrical resistance when they reach a temperature below a certain value (critical temperature).

Today, superconductors are practically used in

Today, superconductors are practically used in physics, where for many

physics,
where for many years large research installations
and

new devices have been used.

In Physics


Слайд 4 Prior to 1986, superconductors with

Prior to 1986, superconductors with this property at very

this property at very low temperatures, below -259 °

C, were known. In 1986-1987, materials were found with a superconducting transition temperature of about -173 ° C.

Слайд 5 Injection of superconductors on an impurity
The introduction of

Injection of superconductors on an impurity The introduction of an impurity

an impurity into the superconductor reduces the sharpness of

the transition to the superconducting state. In normal metals, the current disappears in about 10-12 seconds. In a superconductor, a current can circulate for years (theoretically 105 years!).


Слайд 6 One of the main differences between

One of the main differences between superconductors and ideal conductors

superconductors and ideal conductors is the Meissner effect, discovered

in 1933. The phenomenon was first observed in 1933 by German physicists Meissner and Oxenfeld

Слайд 8 In power applications, superconductors can reduce

In power applications, superconductors can reduce energy losses and reduce

energy losses and reduce the weight and size of

equipment.

Слайд 9 In 10-20 years, superconductivity will be

In 10-20 years, superconductivity will be widely used in energy,

widely used in energy, industry, transport and much wider

in medicine and electronics.      In electronics, superconductivity will find wide application in computer technology. Potentially the most profitable industrial application of superconductivity is associated with the generation, transmission and efficient use of electricity.

Слайд 10 Engineers have long thought about how it would

Engineers have long thought about how it would be possible to

be possible to use huge magnetic fields created with

the help of superconductors for the magnetic suspension of a train (magnetic levitation).

Слайд 11

In the long

In the long term, joint projects for the

term, joint projects for the construction of cryotransport and

railways are possible. The possibility of accelerating macroscopic objects by the electromagnetic field will also find application at aerodromes and cosmodromes, where the SP magnets will provide take-off / landing to aircraft and spacecraft.
