9.9 Applications of superconductivity
Superconductors find many applications. Some of them are mentioned below:
9.9.1 Magnetic applications
a. Superconducting magnets
Similar to electromagnets, superconducting magnets can also be formed by using coils of wire made up of superconducting material. To obtain magnetic fields from electromagnets, current should be maintained in the coil, whereas in superconducting coils, current once introduced into the coil will remain for a very long time and during this period magnetic field can be obtained, provided the temperature of the coil is maintained below its transition temperature [usually at liquid helium temperature]. The benefit of using superconducting magnets instead of electromagnets is the cost ...
