Thermal stability of an immersion-cooled single-pancake superconducting coil has been numerically analyzed. The unsteady heat-conduction equation with source terms allowing for heat conduction across electric insulation film, thermal disturbance, helium cooling and Joule heat generation has been solved. The effect of the transport current, the magnetic flux density, and the energy density, duration, and spatial size of thermal disturbance on the stability of a superconducting coil is clarified.
