At one point in "Provenance," Larry and Amita watch as Charlie holds a battery with a screw attached by a tiny magnet to the (+) terminal. As he touches the (-) terminal with a copper wire, the screw spins. Like Larry and Amita, people have long been fascinated with the properties of magnets.
Students will have an opportunity to explore what happens to the strength of a magnet as you move farther away from it.
