WebAn ideally hard superconductor is a type II superconductor material with an infinite pinning force. In the external magnetic field it behaves like an ideal diamagnet if the field is switched on when the material is in the superconducting state, so-called "zero field cooled" (ZFC) regime. In the field cooled (FC) regime, the ideally hard ... WebSuperconductors can be utilised in one of two ways to produce high magnetic fields. A solenoid can be wound from a hard superconducting wire, tape or cable. This requires that the superconductor, at some stage, be flexible and capable of being wound. A solenoid developing 107 kOe has been made in this way136.
