Abstract: In electromagnetic armor, a shaped charge jet is disrupted when a large current is passed through it while the jet is in contact with two parallel flat plates. For the current to increase as quickly as possible to an effective level, the inductance of the circuit must be controlled or at least known. This inductance, however, depends on the position of the current connections to the plates and the position of the shaped charge jet. A method to calculate this inductance is presented, which is verified by experimental measurements.
