Permanent-Magnet Structuroscopes under Rotational Magnetization Reversal in a Material

Abstract

Dependence of the readings of the sensor in a permanent-magnet structuroscope with a two-pole magnetizing device has been investigated for different directions of the magnetic-field transducer sensitivity axis with respect to the magnetization of a test article. The possibility for the devices to operate in a sensor rotation mode has been shown as applied to testing the mechanical properties of articles and the stressed-strained state of objects made of ferromagnetic materials.
