Magnetism

We are currently learning all about magnets and this week students learned ways to make an electromagnet stronger. There are 3 ways and students learned these quickly when trying to create their own. 

Electromagnets

When an electric current flows in a wire it creates a magnetic field around the wire.

By winding the wire into a coil we can strengthen the magnetic field. Electromagnets are made from coils like this.

Making an electromagnet stronger

We can make an electromagnet stronger by doing these things:

• wrapping the coil around an iron core
• adding more turns to the coil
• increasing the current flowing through the coil.
