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.

Front

What are the two types of magnetic poles?

Back

North Pole and South Pole.

Front

What happens when like poles of two magnets are brought together?

Back

They repel each other.

Front

What happens when opposite poles of two magnets are brought together?

Back

They attract each other.

Front

What is a magnetic field?

Back

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

Front

What do magnetic field lines indicate?

Back

The direction and strength of the magnetic field.

Front

What is the unit of magnetic field strength?

Back

Tesla (T).

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

By increasing the current, adding more coils of wire, or using a ferromagnetic core.

Front

What is the right-hand rule in magnetism?

Back

A method to determine the direction of the magnetic field around a current-carrying conductor.
