Rotational magnetisation

Stan Zurek, Rotational magnetisation, Encyclopedia Magnetica, E-Magnetica.pl

Rotational magnetisation - a type of magnetisation in which the excitation changes direction in a rotational manner. This is different from alternating magnetisation, where the direction is mostly constant, only just amplitude changes (e.g. as in transformers).

Animation of rotational magnetisation, made from data measured for grain-oriented electrical steel, circular B of 1.7T, 50 Hz Animation of differences between power loss measured under clockwise and anticlockwise rotational magnetisation. The differences are caused by angular misalignment of B and H sensors in a fieldmetric method1)
