Abstract
Magnetic shielding currents having a critical current density, Jc, at a superconducting temperature are stabilized by reducing the temperature of the superconducting body after a steady state or persistent current is established. The current density of the current at the reduced temperature is below the critical current density for the material at the reduced temperature. Decay of the magnetic shielding current at the reduced temperature is significantly reduced.
