What is a temporary magnet?

Back

A temporary magnet is a material that can become magnetized when in contact with a magnet but loses its magnetism when the external magnetic field is removed.

Front

What are the two poles of a magnet called?

Back

The two poles of a magnet are called the north pole and the south pole.

Front

Is glass magnetic or non-magnetic?

Back

Glass is non-magnetic.

Front

How many poles does a magnet have?

Back

A magnet has two poles.

Front

What is magnetism?

Back

Magnetism is a type of force that can attract or repel certain materials, primarily metals like iron.

Front

What materials are typically attracted to magnets?

Back

Materials that are typically attracted to magnets include iron, nickel, and cobalt.

Front

What is the difference between a permanent magnet and a temporary magnet?

Back

A permanent magnet retains its magnetism over time, while a temporary magnet only exhibits magnetic properties when in the presence of a magnetic field.

Front

What is the magnetic field?

Back

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

Front

What happens when you cut a magnet in half?

Back

When you cut a magnet in half, each half becomes a new magnet with its own north and south poles.

Front

What is the right-hand rule in magnetism?

Back

The right-hand rule is a mnemonic for understanding the direction of magnetic force, current, and magnetic field in electromagnetism.
