What is electromagnetism?

Back

Electromagnetism is the branch of physics that deals with the interaction between electric charges and magnetic fields.

Front

How can you make an electromagnet stronger?

Back

You can make an electromagnet stronger by increasing the number of coils of wire around the core.

Front

What happens when an electric current flows through a wire?

Back

A magnetic field is created around the wire.

Front

What is the relationship between the strength of a magnetic field and its ability to attract metal objects?

Back

As the strength of a magnetic field increases, the ability to attract metal objects increases.

Front

What do we call the magnetism created by an electric current?

Back

Electromagnetism.

Front

Which devices use electromagnets?

Back

Devices such as speakers, headphones, and doorbells use electromagnets.

Front

What is a magnetic field?

Back

A magnetic field is an invisible field around a magnet where magnetic forces can be felt.

Front

What is the role of a core in an electromagnet?

Back

The core, often made of iron, enhances the magnetic field created by the coils of wire.

Front

What is the effect of using a thicker wire in an electromagnet?

Back

Using a thicker wire can reduce the resistance, allowing more current to flow and potentially increasing the strength of the electromagnet.

Front

What is the principle behind electric motors?

Back

Electric motors operate on the principle that a current-carrying wire in a magnetic field experiences a force.
