My high school textbook, I suppose. Thanks for a good hint.
Let me follow it? As one end of the bar magnet comes closer
to another it induces "poles of the opposite kind" at the surface.
It is similar to what happens in many dielectric materials. The
net pole becomes stronger at each bar magnet and the attractive
force between them changes more rapidly with the distance
than the 1/r^2 law [yes, for ideal monopoles] would suggest.
That is why magnets come toward each other suddenly.
That's not a good way to think about it.
