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.
