The Science of Magnetic Materials and Electromagnets

It's likely there's a magnet wherever you're looking right now. In fact, the device you're using to listen to this episode? Also uses a magnet. Which is why today, NPR science correspondent Geoff Brumfiel is taking us "back to school," explaining how magnetism works and why magnets deserve more respect.
