That's Just Plain Nuts! Materials


Product Description

A cool optical illusion and introduction to magnetic induction. You are going to suspend a stack of hex nuts using a pair of book magnets, demonstrating that magnetic fields can be induced in iron objects. To do this you have to set up an arrangement where the magnetic field of the book magnets has influence over, but is not actually touching, the nuts. When you get it just right it produces a lot of smiles.
