Electromagnets

Learners can:

• explain how magnetic and electric forces are related

• build a simple electromagnet

If you could have a time machine, where would you go and what would you do?

​Is Oxygen Magnetic?

Let's Find Out!

An electromagnet is an object that acts as a magnet when electricity passes through it. Electromagnets generally produce stronger electric force than a standard magnet.

Electromagnets come in many sizes and shapes. However, all electromagnets contain:

• power source

• copper wire

• iron core

​

​Electromagnets

The wire coiled around the iron core of an electromagnet is called a solenoid. Solenoids cause electromagnets to produce stronger magnetic fields than electromagnets without solenoids. The more coils, or turns, in a solenoid, the stronger the magnetic force it will produce.
