How Do You Calculate the Force Between Two Magnets?

[s1c0]

I know I am not doing collage or uni stuff but this is more advance stuff that that by a little bit.

Does anyone know an equation for the force between 2 magnets. the only one we get is for a magnet and a wire f=ILBsinΘ.

This is to help me with an investigation with an electro magnet and a perma magnet.

Any info will help. Thanks.

It depends on the geometry of the situation.
