A motor and a generator are usually needed for converting the forms of energy between mechanical and electrical in some applications. Recently, we have proposed an energy conversion/storage device based on a unique interacting behavior between a permanent magnet and a closed superconducting coil.
Superconducting magnetic energy storage (SMES) is one of the few direct electric energy storage systems. Its specific energy is limited by mechanical considerations to a moderate value (10 kJ/kg), but its specific power density can be high, with excellent energy transfer efficiency. This makes SMES promising for high-power and short-time applications.
Recently, an interesting phenomenon has been found that the electromagnetic interaction between a permanent magnet (PM) and a closed superconducting coil seems to disobey the Lenz''s law . To be specific, the induced current in the superconducting coil does not always oppose the motion of a PM.

The cooling structure design of a superconducting magnetic energy storage is a compromise between dynamic losses and the superconducting coil protection . It takes about a 4-month period to cool a superconducting coil from ambient temperature to cryogenic operating temperature.
A SMES unit stores energy in the magnetic field created by a current circulating in a superconducting coil. At temperatures below the critical transition value, T c, the electrical resistance of the superconducting tape drops to zero, enabling the magnet to carry high currents without ohmic losses.When charging the unit, the current increases, leading to an increase in
Storing energy by driving currents inside a superconductor might be the most straight forward approach – just take a long closed-loop superconducting coil and pass as much current as you can in it. As long as the superconductor is cold and remains superconducting the current will continue to circulate and energy is stored.
Superconducting magnetic energy storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil that has been cryogenically cooled to a temperature below its superconducting critical temperature. This use of superconducting coils to store magnetic energy was invented by M. Ferrier in 1970.
This system includes the superconducting coil, a magnet and the coil protection. Here the energy is stored by disconnecting the coil from the larger system and then using electromagnetic induction from the magnet to induce a current in the superconducting coil.
As long as the superconductor is cold and remains superconducting the current will continue to circulate and energy is stored. The (magnetic) energy stored inside a coil comes from the magnetic field inside the cylinder.
Above a certain field strength, known as the critical field, the superconducting state is destroyed. This means that there exists a maximum charging rate for the superconducting material, given that the magnitude of the magnetic field determines the flux captured by the superconducting coil.
In order to demonstrate Superconductor Magnetic Energy Storage (SMES) is the classroom we can take a Quantum Levitator and induce currents in it. These currents persist as long as it remains cold. We can use a regular compass to verify their existence.
