Fun with Magnets
I’ve done several of these, including a version of the homopolar motor. The eddy current damping is fun, too — you can make nonmagnetic metals react to magnets by inducing current flow in them. Lenz’s law.

Physics, tech and humor. Because science and learning are cool, and life’s too short not to laugh.
