A heater placed on, or within, the windings of a superconducting coil. The heater is activated when a quench condition is detected in the coil or a set of connected coils. This causes a quench region to occur at the location of the heater for quench protection. The heater is electromagnetically inductively coupled to the coil windings, as opposed to relying on thermal diffusion as in conventional heaters. The action of the inductive heater is much faster, so it can be used with REBC0-HTS coils that are fabricated with the No Insulation technique.
