Attraction and repulsion between two magnets

[kalesh]

Hi,
I hope this is the correct place to ask this.
Does anyone know of a formula to calculate the force of attraction or repulsion between two magnets of diffirent sizes and strengths?
Also the magnets are not parallel to each other.
Any help highly appreciated.

It depends on the specific dimensions, locations and orientation of the magnets.
Give some specifics.

Hmmm, okay. Let's say you have two cylindrical magnets of length, L, radius, r, relative permeability k. What else do you need to know? Would you need to know how many Tesla are measured at different distances from the material? Would it help to know the magnetic "moment" of the magnets? Can you model it as though the magnets each consisted of two "monopoles," each subject to an Force = inverse square distance law?

There is info about the torque all over the place, but its hard to find anything about the attraction and repulsion of magnets.
