Magnets and Electricity
Magnets can be big or small. Tiny magnets can hold your artwork on the fridge. A compass magnet is able to point to the Earth's magnetic north pole. Magnets have a magnetic field around them. This magnetic field can create electricity, using a device like a generator.
Turn on a flashlight, a toaster, or a TV. All these things use electricity. Electricity is made when positive and negative charges come into contact with each other. Nowadays, there are even some cars that can run only on electricity.
