Abstract
Abstract An electric pulse generator utilizing a Matteuci effect. An alternating magnetic field is applied to distorted magnetic substances by a permanent magnet rotor, a polarizedly magnetized running sheet or an electric coil. The amorphous magnetic substances generate sharp pulse voltages between its ends, at the specific phase of the alternating magnetic field.
