ATTACHABLE FERROMAGNETIC COERCIMETER Russian patent published in 2004 - IPC

FIELD: magnetic measurements technology.

SUBSTANCE: device has U-shaped core with magnetizing and demagnetizing windings, indication element in form of ferromagnetic collecting counter and comparing device. Indication element is made in form of two ferromagnetic collecting counters with collection coefficients changing in opposite directions of elements, mounted on side rods of U-shaped core, outputs of which are connected to input of comparing device, and magnetizing as well as demagnetizing winding is mounted on middle rod. Measured value is determined by difference of frequencies of ferromagnetic collecting counters in comparing device.

EFFECT: higher precision of measurements and higher sensitivity.
