I keep going back to this, but I get confused when imagining everything. I'll start off with a motor: Basic set-up fixed magnets of a uniform magnetic field and a conductive armature that has current flowing, the armature experiences a torque(due to the the Lorentz force), and the armature gains speed, the initial opposing "force"(not actual force, just found the word easier to describe the system) to the change in magnetic flux(area in this case) would be counter-electromotive force that would reduce the applied current and the motor reaches high speeds. Since there is current flow within the armature there is a generated magnetic field surrounded by the exterior magnetic field of the magnets, is there any form of magnetic repulsion/attraction going on? I keep thinking about it a lot... they are basically two magnets, the armature experiences two simultaneous phenomenons occurring, the Lorentz force, and back-emf, is the magnetic attraction/repulsion a third? The same goes if we switched it around, making the magnets rotate around and the electromagnets fixed. Would the electromagnets/magnets creating the uniform magnetic field undergo any forces? I always ignore the sources the create the magnetic field, all the action happens to the conductive rotor! Likewise, for a generator when there is a load. And current begins to flow, there is a Lorentz force opposing the change in flux, is there a form of magnetic force here two? I feel that sometimes I don't account for everything in such systems, which I'm planning to work on in the future.
