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 magnets?

Back

The two types of magnets are permanent magnets and temporary magnets.

Front

What is a permanent magnet?

Back

A permanent magnet is an object that maintains its magnetic properties over time without the need for an external power source.

Front

What is a temporary magnet?

Back

A temporary magnet is a material that exhibits magnetic properties only when in the presence of a magnetic field.

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 materials are commonly used to make permanent magnets?

Back

Common materials include iron, cobalt, and nickel.

Front

What happens to a magnet when it is heated?

Back

Heating a magnet can cause it to lose its magnetism, a process known as demagnetization.

Front

What is the magnetic field?

Back

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

Front

What is the rule for magnetic poles?

Back

Like poles repel each other (N-N or S-S) and opposite poles attract each other (N-S or S-N).

Front

What is a natural magnet?

Back

A natural magnet is a magnet that occurs in nature, such as lodestone, and is a permanent magnet.
