BROCKHAUS has developed the Rotational Power Loss Tester, which is an equipment to measure the magnetic properties under rotational field. Therefore, in the case of two dimensional measurements, especially under rotational flux, the vector components of the flux density B are kept sinusoidal in time t. By adjusting the amplitude and the phase of the components, every mode of polarization can be achieved in the range from purely alternating flux in an arbitrary direction with respect to the rolling direction, to purely rotational flux with constant angular velocity including circular or elliptically rotation.
