Magnetism

Front

What is magnetism?

Back

Magnetism is a physical phenomenon produced by the motion of electric charge, which results in attractive and repulsive forces between objects.

What is a magnetic pole?

Back

A magnetic pole is one of the two ends of a magnet where the magnetic force is strongest. There are two types: North and South poles.

Front

What happens when like poles of magnets are brought together?

Back

Like poles repel each other; for example, North repels North and South repels South.

Front

What happens when opposite poles of magnets are brought together?

Back

Opposite poles attract each other; for example, North attracts South.

Front

What is a compass?

Back

A compass is a navigational instrument that shows direction relative to the Earth's magnetic poles.

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

How can the strength of an electromagnet be increased?

Back

The strength of an electromagnet can be increased by adding more coils of wire or increasing the electric current.

Front

What is electric current?

Back

Electric current is the flow of electric charge through a conductor, measured in amperes.

Front

What is a magnetic field?

Back

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

Front

What is the relationship between electricity and magnetism?

Back

Electricity and magnetism are interrelated; electric currents produce magnetic fields, and changing magnetic fields can induce electric currents.
