...motor. A homopolar motor moves when you power the coil, strictly by electromotive force. Our coil is going to be sandwiched between two axially magnetized magnets, just like a Faraday disk, but in a homopolar generator style - it will move along with the magnets when spun, no field line crossing. I will not get into more details, but assume that the coil is being powered from a DC source. Given that the source is DC, Lorentz forces will keep their direction. However, given that the coil is moving with the magnets, the configuration of the forces will always be the same, not rotating on a 360 degree pattern. My model presumes two half toroids with rectangular turns. I modelled, in a crude fashion, current interaction with the field lines from both magnets, as well as ...
