What is Electromagnetism?

Back

Electromagnetism is a branch of physics that studies the interaction between electric charges and magnetic fields.

What is a conductor?

Back

A conductor is a material that allows electric current to flow through it easily, such as copper or silver.

Front

Which material is not a good conductor?

Back

Plastic is not a good conductor of electricity.

Front

How can you make an electromagnet stronger?

Back

You can make an electromagnet stronger by adding more wire coils and/or batteries.

Front

What surrounds a wire when electric current is flowing through it?

Back

A magnetic field surrounds the wire when electric current is flowing through it.

Front

What happens when you increase the number of coils in an electromagnet?

Back

Increasing the number of coils in an electromagnet will increase the power of the magnet.

Front

How can a magnet produce an electric current?

Back

A magnet can produce an electric current by being spun around inside a coil of wire.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet that is created by electric current flowing through a wire coil.

Front

What is the relationship between electricity and magnetism?

Back

Electricity and magnetism are interconnected; electric currents create magnetic fields, and changing magnetic fields can induce electric currents.

Front

What is a magnetic field?

Back

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