What Makes Magnets Stick to Things?

Magnets work because their atoms are lined up in the same direction, creating a magnetic field. When they meet certain metals like iron, their fields connect and they stick.

You can think of each atom like a mini magnet. When all those mini magnets point in the same direction, they team up to create one strong magnetic force.

When a magnet gets close to something made of iron, it pulls the atoms in that object into alignment, too—at least temporarily. That’s why your magnet snaps to the fridge and holds your artwork in place!

But not everything sticks. Magnets won’t work on things like plastic, wood, or even some metals like aluminum. That’s because their atoms aren’t the kind that respond to magnetic fields.

Some coasters use magnetic brakes and motors for smooth, fast acceleration and stopping—with no friction at all!
