Electromagnets are really fascinating!

They work by sending an electric current through a coil of wire. When this happens, a magnetic field forms around the wire.

What’s cool about electromagnets is that you can turn their magnetism on and off just by changing the flow of the current.

Here are some key points to remember:

• Coil of Wire: This is just wire that is looped around.
• Electric Current: This flow of electricity creates the magnetic field.
• Switchable: You can easily control when the magnet is on or off.

Because of these features, electromagnets are super helpful in many areas. You can find them in scrapyards, maglev trains, and electric motors!
