Abstract
A Barkhausen probe includes a magnetizing field generator, a magnetoresistive magnetic field sensor, a direct current power supply for biasing the magnetoresistive magnetic field sensor and signal conditioning electronics. The Barkhausen probe is capable of generating and sensing the Barkhausen noise emanating from the surface of a cyclic magnetized specimen. The conditioned Barkhausen noise output of the signal conditioning electronics is usable as input to various analysis systems where textural analysis of the material can be performed.
