| When superconductors are in the superconducting state, in which temperature,
magnetic field and current become lower than a critical value, its electrical
resistance becomes zero. Although superconducting wire rod requires a cooling
system to maintain a low-temperature state, having features such as high
current density and extremely low loss, it has a lot of advantages in terms
of energy and environment. The electrical resistance in the superconductor
becomes zero, when DC is applied, but when AC is applied, loss is caused
in a superconductor. In JMAG, the AC loss in a superconductor can be obtained.
This note presents the use of magnetic field analysis to obtain the AC
loss in a superconductive filament. |
