I'm taking physics 2 and was told to create a practical project utilizing electromagnetic force. Starting thinking about Lenz's law (which I just read in a text book for the first time a week ago) and I thought it would be fun to send a pinewood derby car uphill instead of down. The sprinkler pump had a bad capacitor from standing water and a lot of other connections were rusted up pretty good. I haven't tested the windings yet but I assume they are okay. The idea is to hook the well pump's coil to a battery and use the induced field to accelerate a magnetic car down a track. I took the windings from an A/C motor but that shouldn't matter right? I can just hook them directly to a D/C battery? Should I just plug it into the wall? I don't want to start a fire but I don't know my boundaries. Am I a crazy person? Will this work? Thoughts/criticism/safety concerns/prayers? See two attached photos of current progress. This is my first post on Physics Forums so I'm not 100% on how image posts work here. Help or advice of any kind is appreciated, even if it's mean. I understand I'm playing with fire and could seriously hurt myself, so don't don't sugar coat it.
