Hmmm. I've never actually heard of a magnetic dipole moment or its potential energy. Apparently this question is supposed to be solved using solely equilibrium equations and electromagnetism equations which don't already include torque.
Thanks for trying to help though.

Homework Equations
I found a formula that makes this question seem a lot easier. Torque = NIAB. however, this formula is not on the formula...
