Magnets are fascinating. They provoke our curiosity. By touching one to a straight pin, you create an instant compass. Use it to map magnetic fields around a small magnet, or a whole planet. What else can you do with this pin? Re-magnetize it, chop it into pieces, heat the attracting fragments in a candle flame. These experiments reveal much about the nature of magnetic domains. Add coiled wire and dry cells to your magnets to create a surprising array of wonderful inventions; electromagnets, solenoids, telegraphs, buzzers, motors, generators & relay switches. Magnetism is great science, and great fun. Includes two ceramic magnets. For grades 8-12; adaptable for younger students.
