DEVICE FOR REPRODUCING ALTERNATING MAGNETIC FIELD Russian patent published in 2006 - IPC G01R33/00 

Abstract RU 2271548 C1

FIELD: magnetic measurements, possible use for creating sources of alternating magnetic fields.

SUBSTANCE: device for reproducing alternating magnetic field has circuit for limiting voltage increase speed, amplifier, two inductiveness coils, resistor, rectifier, memorizing device, rectangular pulse generator, two digital-analog converters, two registers, five analog keys, six supporting voltage sources, seven comparators, logical element NOT, twelve adding amplifiers, four analog memorization devices, three analog multipliers, two analog splitters, multiplexer, logical element 4-OR, four storage triggers, four logical elements OR, four analog models, device for taking square root, device for determining minimal value, channel for measuring strength and priority encoder.

EFFECT: due to possibility of decrease of number of measured points of hysteresis curves while maintaining unchanged error of approximation of output data, measurements time is reduced.
