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
original?
