An experiment with a magnet.
The magnet spends energy on overcoming the ohmic resistance of the winding wires.
Heating the magnet, preventing it from working.
If you take a superconducting material for the winding and cool the coil to the temperature of liquid helium, the current will flow without resistance.
Nails are magnetized to the body with the coil.
Such a magnet can be disconnected from the network, disconnect the conductive buses, and it will continue to work.
The opening key is attracted to the magnet.

Cartoon explaining the processes of energy accumulation.
Assembly of a superconducting energy storage device in the laboratory.
Academician Sychev tells the story.
Pilot-industrial installation built at the Institute of High Temperatures of the USSR Academy of Sciences.
Electric energy can be generated by a stream of hot plasma passing through a magnetic field.
This unusual magnetohydrodynamic MHD generator does not have the usual rotor and stator.
With a high efficiency, heat is converted directly into electricity.
Such a device needs a magnet, but a very large electric one.
A magnet in a cryogenic jacket, superconducting, is suitable.
Such a magnet is demonstrated.
It is more powerful and much more compact than an electric one.
