Abstract
A rail gun projectile includes superconducting material. Current from a DC power supply flows between the rails through the superconducting material with a component at right angles to the elongated direction of the rails. The superconducting material is of a type that the current flowing through it produces a force for driving the projectile longitudinally along the rails. Metal abutting against the superconducting material shunts current from the power supply around a portion of the superconducting material having a tendency to go normal to the remainder of the superconducting material in the superconducting state.
