The MAGracing Car

The Steering System
The steering is done by controlling a coil, switching the current, changeing the polarity of the coil, causing the movement of 2 magnets placed on the steering arm, that moves the front wheels.
The steering is not proportional and is also not needed, because the car will be following a wire under the track. When the car is off the wire, it can be steered back to the line with this simple steering, that can go full Left or full right, enough steering to get the car right back on track. The cars also have a reverse function.
The steering arm under the car keeps the car on the track, by following the metal wire under the track.
