Flux resetting of several magnetic materials

THIS ARTICLE deals with the flux resetting characteristics of several magnetic materials commonly employed in magnetic amplifiers. In this study the flux was forced to change under the influence of a constant external magnetizing force. The operation of a core employed in self-saturating magnetic amplifier circuits with high-impedance control windings approximates these conditions during the nonconducting half-cycle of supply voltage. The data collected therefore are readily applicable to studying this type of magnetic amplifier.
