Characteristics of Superconducting Magnets

Since the current densities are high, superconducting magnet systems are quite compact and occupy only a small amount of laboratory space. Another feature of superconducting magnets is the stability of the magnetic field in the persistent mode of operation. In the persistent mode of operation, the L/R time constant is extremely long and the ...

Superconducting magnetic energy storage - Wikipedia

Superconducting magnetic energy storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil which has been cryogenically cooled to a temperature below its superconducting critical temperature. A typical SMES system includes three parts: superconducting coil, power conditioning system and cryogenically cooled refrigerator.

Magnetic flux quantum - Wikipedia

The magnetic flux, represented by the symbol Φ, threading some contour or loop is defined as the magnetic field B multiplied by the loop area S, i.e. Φ = B ⋅ S.Both B and S can be arbitrary, meaning Φ can be as well. However, if one deals with the superconducting loop or a hole in a bulk superconductor, the magnetic flux threading such a hole/loop is actually quantized.
