Abstract��In order to overcome the insufficiency of the existing method in quality determination of soft magnetic material, which can only detect standard ring or rod-like samples, an experiment was designed to seek a palatable solution to the problem. For achieving the purpose of shaped quality detection, relevant tests were carried out by using different contrast methods to compare two special-shaped partsin coercive forces of differences between qualified and unqualified special-shaped parts on the 1J50 of soft magnetic material. Experimental results show that there is a clear difference comparison in the two curves which plus unqualified and qualified sample under magnetizing current of 450 or 500 mA and reverse current at about 7 or 5 mA, and this method can be used to distinguish qualified or unqualified samples.
