Impulse Magnetizers

Operates on a stored energy principle where voltage is stored in a capacitor bank,usually requiring several seconds and thestored energy is then discharged through a unidirectional switch (SCR)into a magnetizeing fixture. Duration and wave shape of the pulse is dependent on the capacity of the bank, the inductances of the fixtures and to some extent the resistence of the fixture.

Pulse lenghts of from 100 microseconds to several tens of milliseconds may be obtained and thus extremely high currents and consequently high fields may be obtained without undue heating effects and depending upon the pulse duration which varies with each magnetizer type, the magnetizing field can reach upto 60000 Oersteds.
