In a measuring coil a material sample is exposed to a defined magnetic field and magnetic flux is created in the soft magnetic material. The electric current required is supplied by a power amplifier. The current is measured by means of a clamp-on ammeter.
Determination of the polarization is by sampling of the induced voltage, conversion and integration. Parallel recording of the H and J sizes with separate high speed analogue-digital converters guarantees absolutely simultaneous measurement.
The measurement is performed under sinusoidal polarization. The nominal voltage is supplied by a highly stable, digital frequency generator. Amplitude and frequency are set by software according to the sample data entered and the default values.
