So I know that by Faraday's law, a voltage is produced when there is a changing magnetic field in a coil of wire.
Well, what if one had shocks like for a car. Have a coil around the shocks, and then a magnetic fixed to the shocks. So when the shocks move, the magnet moves, but not hte coil. This would produce a voltage at the ends of the wire.
SO what if one did this to say....an electric car? Every time you went over a pothole, you'd be generating a voltage. You could charge your batteries as you move. If I am not mistaken, the output voltage according to the formula that quantifies Faraday's law is a function of flux density. So if one used a good magnet like a neodymium core from a step motor, I think I would be able to generate a decent amount of voltage.
Is this a glaringly bad idea? Am I missing something? Or could this work?
