What Causes a ‘Magnet’ to Attract Metal and How Is It Used?

Magnets pull metal because of a special kind of invisible power. Imagine you have a magic wand that can pull certain kinds of coins or keys from your pocket, that’s what magnets do! Some metals, like iron and steel, are especially good at being pulled by this magic force. Magnets are used in many things, like fridge doors, toy trains, and even electric cars!
