Demagnetization Procedure for the MBN Magnets

, 2002
Results from demagnetization tests of an MBN magnet are reported here. Following a "texbook" demagnetization procedure where alternating polarity current settings from saturation (1500A) down to 1% of this (15A) are applied, a remnant field of the order ...
