Calculating Magnet Forces at an Angle: Formulas and Book Suggestions

[galbrig2]

I am trying to calculate how much forces is between two magnets, but the catch is they will be approaching each other at an angle.

I have found plenty of information using the model of two magnets heading end to end, but am not sure if the formulas change when the magnets are not in that configuration.

I ma not sure if I am being clear with what I want so if there is any confusion let me know and I will see if I can stat what I am looking for a little better

Also, if anyone can suggest a book which gives a good expiation about the forces between two magnets I would be grateful.

If you can model the two magnets as point dipoles, i.e., each with two magnetic poles +/- q_m separated by a distance L, then you could write the forces as a sum of four vector forces, one between each pair of poles. Two are attractive, two are repulsive. There is almost certainly a torque as well as a force. There is probably a better way, but I don't know it.
