Two friends made a magnet by wrapping a nail around a wire and connecting the wire to a battery. They each had different ideas about why the magnet worked.
Which one do you agree with most?
Kathryn - I think the nail makes the magnet. If we pull the nail out, the magnet won't work anymore. O
Megan - I think it is the wire loops that make the magnet. If you take the nail away, it would still work.
