A flux compression generator (FCG) is provided for producing an electromagnetic pulse (EMP). The FCG includes an environmental case, a reactive load, a dielectric core, a superconducting stator, an electric energy source, a load switch, and a transition device. The reactive load transmits the EMP in response to an electric current pulse. The dielectric core has proximal and distal ends within the case, with the stator disposed coaxially around the core that provides structural support. The case contains the electrical energy source, the stator, the core and the transition device. The energy source connects to the stator at the proximal end and powers the transition device. The load switch connects the reactive load to the stator at the distal end. The energy source initially provides an electric current to the stator. The device upon activation heats at least a portion of the stator to reversibly transition the portion from a superconducting state to a non-superconducting state. The stator transfers the electric current as the pulse to the reactive load upon the portion's transition to the non-superconducting state. The stator can be a superconducting helical coil that wraps around the core connected to a superconducting conductor disposed coaxially within the core. Alternatively, the stator can be a stack of superconducting rings disposed coaxially along the core. The superconducting coil and rings can preferably be composed of a high temperature superconductive material on a metal substrate.
