Electricity, Magnetism and Electromagnetism

Front

What happens when two magnetic South poles are brought near each other?

Back

The magnetic field lines would move out, but then curve away from each other.

Front

What happens when two magnetic North poles are brought close to each other?

Back

They will repel.

Front

What type of charge do protons have?

Back

Positive.

Front

Why is a magnet attracted to a soup can?

Back

Because the can has iron in it.

Front

What is the unit of measurement for resistance in an electrical circuit?

Back

Ohms.

Front

What is electricity?

Back

Electricity is the flow of electric charge, typically through a conductor.

Front

What is a magnetic field?

Back

A magnetic field is the area around a magnet where magnetic forces can be detected.

Front

What is the difference between conductors and insulators?

Back

Conductors allow electricity to flow easily, while insulators resist the flow of electricity.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

Front

What is the relationship between electricity and magnetism?

Back

Electricity can create a magnetic field, and a changing magnetic field can induce an electric current.
