- All materials are on the bench for each student to create their own motor, including a double-Miller-arm's length of copper wire (Jeff will cut these before each lab).
- The only exception are the small neodymium magnets; they are in a box on the small bench by the sink, and are handed out after the pre-lab discussion
- Handle the magnets with care; they can easily pinch the shit out of your finger, or flake off small pieces
- Students will share wire cutters and Sharpies (used to mark the polarity of their magnet)
- Make sure students identify the correct pole of their magnet. Some still haven't figured out what the compass is telling them!
- Students have a difficult time wrapping the wire coil correctly; I frequently have to help them 'tune' their coil so that it spins properly. Check to make sure the safety pins are making good contact with the battery
- A box of discarded coils is left on the front table; one coil is marked for demo, so I frequently set it up and get it spinning on the front table.
