Okay, so I have a simple D cell battery, enamel coated copper wire loop and a magnet. I can easily get the copper wire loop to spin if I scratch away part of the enamel (that side which touches the stand) off the ends of the wire, run current through a stand, and position the magnet at just the right position. Here's the problem...... When I run a simple electric motor in this fashion, I'm relying on the momentum of the wire to spin back around, hit the magnets magnetic field, then be spun again (which is not efficient) What I need to be able to set up is a simple electric motor like this that allows current to run BOTH ways through the copper wire loop, basically spinning it constantly without having to rely on momentum to spin it back around. I'm having a super hard time figuring out a plan for this pand just wanted to see if anyone could help me out.
