Abstract:
1. A method for magnetizing a magnet system, comprising the steps of: allocating a magnetization coil to the magnet system; impinging a magnetization coil with a current pulse of a limited pulse duration to build a magnetic field interactive with the magnet system; the current pulse being produced by a discharge of a capacitor element which is electrically connected to the magnetization coil, wherein the magnetization coil and the capacitor element are sized and mutually arranged; and leading the current pulse back into a positive terminal of the capacitor element by a return path including an accumulating inductor coil before a recovery diode element arranged parallel to the magnetization coil, wherein a first end of the inductor coil is connected with respect to the positive terminal of the capacitor element, a second end of the inductor coil is connected to a cathode of the recovery diode element, and an anode of the recovery diode element is connected to a ground, whereby an exponential decay of current in the magnetization coil is prevented and electrical energy is recovered in the capacitor to prevent ohmic losses.
