I've been trying to build an electric motor for my 11th grade physics class and I'm having some problem. I'm trying to stay away from using a reed switch because my teacher hinted at a better grade for motors using a split-ring commutator (and because I couldn't find a reed switch anywhere). I've looked through several websites (at least 20) and I can't seem to find any kind of guidelines. All I found were sites explaining the theory and how the split ring commutator works. If anyone could answer a few of my questions and even go beyond that in helping I would appreciate it. 1. How does the direction of the wires being wrapped affect the motor and which direction should they be wrapped? 2.Will the motor be affected my the nail attracting magnets before a current is run through the wire? 3.Along with the magnetic wire, what other types of wire should be used? Thanks to anyone whom helps.
