FIELD: instrumentation.
SUBSTANCE: invention relates to instrumentation, particularly, to determination of the core magnetic parameter, namely the permanent magnetic field component. Part of magnetic flux is branched from the core and fed to shunting part. Note here that magnetic material of magnetic shunting part is not saturated. This results from sensory-analytical device including coil fitted at shunting branch. Magnetic parameter is defined by this branched part of magnetic flux or by its derivative. Obtained results allow the signal filtration.
EFFECT: perfected method.
