About Magnet Lab
Magnets pull on iron, nickel, cobalt and steel, but not on every metal. Stick or not? tests everyday things, from a steel paper clip and a cast-iron pan to an aluminum soda can, a brass key and a gold ring that magnets ignore.
Poles shows two bar magnets and asks whether they will attract or repel: opposite poles pull together, the same poles push apart, and the magnets slide to show it. It also covers why a magnet cut in half becomes two magnets, where a magnet is strongest, and why a compass points north. In Push the car, children choose which pole to point at a car carrying its own magnet, pushing it away or pulling it closer to reach the flag.
Magnets at work shows magnets in hospital MRI scanners, floating maglev trains, recycling centers that pull steel cans from aluminum, junkyard electromagnets, speakers, fridge doors, electric motors and the Northern Lights.
