Abstract	Wire movement in a superconducting coil has been simulated dynamically by means of solving the equation of motion of each winding with time to study the instability of a superconducting magnets. The force applied to each wire considered here were Lorentz, hoop, wire-wire and wire-bobbin interaction. As the transport current was increased, Lorentz force which is calculated as the product of transport current and magnetic field applied to the wire was increased and resulted in the floating of winding from the coil bobbin. The minimum quench energy (MQE) of each winding was also calculated and was compared with the frictional heating. The quench current was defined as the current where the frictional heating exceeds the MQE. The degradation induced by frictional heating can be reproduced. The effect of the misalignment of the wire was also examined. It was found that the misalignment of the coil degraded the quench current.
