DEVICE FOR MEASURING CHARACTERISTICS OF FERROMAGNETIC MATERIALS

摘要

FIELD: measuring engineering. ^ SUBSTANCE: device comprises re-magnetizing winding made of two sections spaced at a distance equal to their radii. The winding comprises the additional compensating winding that is connected with the controllable DC power source and provided with a mechanism for control of magnetic axis. The measuring winding is wound on two frames arranged within the length of the specimen to be tested. The windings are connected with the input of the second amplifier. The magnetic axes of the windings are parallel. The voltage controller and the source of reference power have indicators of the amplitude of the re-magnetizing field and value of the field of remagnetization. ^ EFFECT: enhanced accuracy of measuring. ^ 2 dwg
