FIELD: instrumentation.
SUBSTANCE: invention relates to instruments for measurement of weak heterogeneous magnetic fields. The device operates in the following manner. A circular turn supplied from a high-frequency AC generator with current develops AC magnetic field, which initiates EMF in a measurement coil. The specified EMF is amplified by an AC amplifier and recorded with the help of a secondary measurement instrument.
EFFECT: increased sensitivity of measurement means used during measurement of weak magnetic fields.
