Energy loss from a fluctuating field?

I have read briefly a few times that a fluctuating magnetic field causes a permamagnet to lose its strength faster than usual. Does this happen to a magnet in any instance the field is fluxing or does this loss only a occur with a group of magnets?

Also what constitutes a fluctuating field? Must the magnet be spinning (like that of a flipped coin), stationary - but spun in a wheel, or quick back and forth/up and down repetitions (vibrational motion)?

Anybody have a clue?

As far as my understanding goes, a magnet naturally loses it's field integrity over X period of time.

Exposing the magnet to a separate moving magnetic field literally "drags" the atoms out of magnetic alignment, causing a faster degradation of the field integrity. It doesn't matter if it is a group or one single magnet, the field loss is the same.
