Abstract
A circuit for selectively variably setting the magnetic remanence in a magnetizable core employs flux circuit feedback, including feedback initiating a self-blocking oscillator type of operation, to achieve designs of two or three (as the designer may desire) elementary sequences (referred to in the art as cycles) to erase previous remanent flux density and to set a new remanent flux density. The circuit apparatus is amenable to constructions using single monolithic integrated circuit chip techniques.
