A most compelling and instructive followup to Electricity #32, and every bit as much fun. Students employ simple techniques to discover and map interacting magnetic fields, and to graph the strength of magnetic fields over distance. They build compasses, motors, buzzers, and other ingenious inventions, improvising with refrigerator magnets and cheap, simple stuff. So incredibly little teaches so much! An alltime favorite title with both students and instructors.
