Abstract

1. Method for the treatment of ferromagnetic materials in which the materials (9) are exposed to a pulse magnetic field with certain pulse recurrence frequency, amplitude and length and are demagnetized at the end of the treatment, characterized in that the pulse field is bipolar with a ration of positive and negative amplitudes of 1.8 to 0.2, with the pulses of the one polarity having the same or lower recurrence frequency than the pulses of the other polarity.
