Superconducting coils are made out of very thin (100 micro meter)
superconducting wires. Those superconducting wires are interdented
in a Cu wire. When it goes out of superconducting the current pass
through the Cu. The energy must be very fast (~1 sec) removed.
Bij connecting resistors to the coil, the most of the energie is
disipated in the resistors.  During such event the superconducting
wire going very fast to room temperature.
