ABSTRACT:
The present invention is to provide means to attain an improved current efficiency and a stabilized operation even when used to generate high-power magnetic pulses at shortened pulse intervals. The objective is attainable with an apparatus to generate magnetism, comprising a plurality of magnetism-generating circuits which are cascaded each other, each magnetism-generating circuit containing a coil member to generate magnetism and a capacitor to provisionally store the current across said coil member; and a conduction-controlling circuit which is to operate the magnetism-generating circuits in a prescribed order.
