Magnets are fascinating. They provoke our curiosity. Touch a magnet to a straight pin to make another magnet. Hang this pin on a thread to make a compass. Use it to map magnetic fields around a small magnet, or a whole planet. Reverse poles on your pin, chop it into pieces, heat the attracting fragments in a candle flame. These experiments reveal much about the nature of magnetic domains. Create a surprising array of wonderful inventions: electromagnets, solenoids, telegraphs, buzzers, motors, generators and relay switches. What fun (and great science)!
