Technical drawing of Cam design: Design a cam that follows the outer circumference of the wheel. The cam will have raised and lowered sections corresponding to the desired "on" and "off" states of the switchable magnets. Attach the cam securely to the wheel so that it rotates along with the wheel. Lever and switchable magnet connection: Design a lever that will interact with the cam. One end of the lever will follow the cam's profile, while the other end will be connected to the switchable magnet's mechanical switch. Mount the levers using pivot points around the circumference of the wheel, in line with each switchable magnet. Ensure that the levers are properly aligned so that when the cam's raised sections push against the levers, the magnets are in the "on" state, and when the cam's lowered sections allow the levers to move away, the magnets are in the "off" state. | Anything
