What would be the best strategy in solving the following problem: Given 2 small rectangular magnets, approx 5 feet of wire, 2 thumb tacks, 2 paper clips, and a small block of wood (about 4"X2"x.5") How would one built a motor so that it can at least reach 2600 rpm. Only these items can used, the use of glue, tape, etc will disqualify you. NOTE only these items can used in thethe motor but you can use a drill to make holes or a saw to cut the wood in building the motor etc. send suggestions to yphotons@athena.mit.edu

There was a lovely motor project using just those parts... Maybe you can earn your gold arrow point for it. BTW: Tape is useful to hold the wire that becomes the commutator. I guess that disqualifies me. Marc Kaufman (kaufman@polya.stanford.edu)

Only Ask any high school physics student who has done this as part of a class (I think it is a fairly common lab project, at least it was at out high school). Manuel.
