Students teams each use a bar magnet, sheet of paper and iron shavings to reveal the field lines as they travel around a magnet. They repeat the activity with an electromagnet made by wrapping thin wire around a nail and connecting either wire end to a battery. They see that the current flowing through a wire produces a magnetic field around the wire and that this magnetic field induced by electricity is no different than that produced by a bar magnet. The experience helps to solidify the idea that electricity and magnetism are deeply interrelated.
