Only if you had plastic wire. The PWM controls work with pulses which causes a constantly changing magnetic field. And just so you know, the compasses sold through digikey are over $300, far surpassing the custom electronics budget

By George I have figured out the problem.  Wrap the wires around each other. The magnetic fields will actually cancel each other out. As for the motors putting capacitors across them should help out on interference. As for the price I have found a company that makes fairly cheap compass sensors. Yeah this is not for first but another robotics project of mine.
