Re: [Phys-L] breaking magnets

Ok, that's a lower bound. But is the force at any given distance provided by the combination of 2 disc magnets on some object = twice the force of one disc magnet at the same distance on the same object? Or is it greater/less than twice the force of one disc magnet? My quick and dirty model says "=", but "slightly greater" wouldn't surprise me.

KC suspects that the JC's answer wasn't actually what the questioner was asking.

If you put together 2 disc magnets, the resulting magnet is stronger than either individually. This is easy to test if they have a hole in the middle and you put a magnet opposing them on the top.

If you break a simple dipole bar magnet in two unequal pieces, how
does the strength of the pieces relate to the strength of the
