Hi all, I'm trying to construct a simple battery-powered electric car. I have a simple, albeit working, motor with a 9V battery, ceramic magnets, and a coil made of thin magnetic wire. When the circuit is closed and I put the magnets in some location underneath the coil, a simple flick will get it spinning. Now my question is how can I turn this into mechanical energy that can turn an axle? I'm having trouble hooking up such thin magnetic wire to the axle with wheels. The wheels are small rubber ones from a toy car, so I could always change that. Right now the motor is simply built on a cardboard base, so I'm just having trouble with the logistics of actually utilizing the motor. I'm fairly inexperienced at physics, especially a project like this, so any advice would really be appreciated. Thank you!
