ABSTRACT:
A device for testing the magnetic properties of a magnetic material in which a measurement air gap and a measurement compensation air-gap, is established and a measuring coil is provided for collecting a voltage which is proportional to the variation of amplitude of the resultant useful flux derived from the magnetic material which is placed in the vicinity of the measurement air-gap.
