magnetizations

If the spacer size is chosen appropriately, the magnetic layers will have opposite magnetizations:

This process accelerates until the plasma is intensely hot and the magnetic field lines of flux are compressed to huge magnetizations.

A Dark, Misleading Force Sean 2007

Hard iron and steel retain previous magnetizations, and an apparent external neutrality would in most cases be the superposition of one magnetism upon another of equal external force in the opposite direction, as shown at B, Fig. 1.
