modelling the force field of multiple magnet bars |
Hi all,
I have several magnets (bars) of well known size.
These magnets are placed on a table and they can rotate around their
center until they reach a stable state.
I want to know if there are some mathematical formulas which can
describe the interaction in this system.
I've found a formula which describes the force between two identical
cylindrical bar magnets placed end-to-end.
But, I need a more general formula where multiple magnets are involved
and are not always placed end-to-end.
Is there such formula?
thanks,
laura

In general, no, there isn't.
