Good opportunity to learn some physics.
Don’t know if they are the right type of magnets do to their shape, but you could get some thick copper plating, large copper tubing and bare copper wiring and demonstrate some of Faraday’s laws of induction and Lenz’s laws on magnetic principles. Cool stuff for grade school age kids.
