Abstract

A device for magnetizing a magnet system preferably having several pulse-generator circuits which are mutually arranged so that their magnetic fields superimpose in a cumulative manner. Each pulse-generator circuit includes a capacitor element, a magnetization coil electrically connected to the capacitor element and a switch element by way of which actuation the magnetization coil can be impinged with a current pulse of a limited pulse duration arising by the discharge of the capacitor element, and thus the build-up of a magnetic field may be triggered. The pulse-generator circuit is built up so that the pulse duration of the current pulse is limited to a value between 10 .mu.s and 500 .mu.s. With such short pulse durations, undesirable heating of the magnetization coil is short so that the device may be applied in automatic production installations with cycle times of below 1 s.
