Understanding Magnetism

Front

What is a permanent magnet?

Back

A permanent magnet is an object that consistently produces a magnetic field and can attract ferromagnetic materials like iron, regardless of external influences.

Front

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 materials can be attracted by a magnet?

Back

Materials that can be attracted by a magnet typically contain iron, nickel, or cobalt.

Front

What is the difference between attraction and repulsion in magnetism?

Back

Attraction occurs when two magnets pull towards each other, while repulsion occurs when two magnets push away from each other.

Front

What is the role of poles in a magnet?

Back

Every magnet has two poles: a north pole and a south pole. Opposite poles attract each other, while like poles repel.

Front

What happens when you cut a magnet in half?

Back

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

Front

What is ferromagnetism?

Back

Ferromagnetism is a property of certain materials that can become magnetized and retain their magnetism even after the external magnetic field is removed.

Front

What is the magnetic field?

Back

The magnetic field is the region around a magnet where magnetic forces can be detected and is represented by field lines.

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 you create a temporary magnet?

Back

You can create a temporary magnet by rubbing a magnet against a ferromagnetic material, like a nail, in one direction.
