What are magnetic domains?

Back

Magnetic domains are small regions within a magnetic material where the magnetic fields of atoms are aligned in the same direction.

Front

Do all objects have magnetic domains?

Back

No, not all objects have magnetic domains. Only certain materials, like iron, cobalt, and nickel, have magnetic domains.

Front

What is a magnetic material?

Back

A magnetic material is a substance that can be magnetized or attracted to a magnet, such as iron.

Front

Can a magnet exert force on all types of materials?

Back

No, a magnet can only exert force on magnetic materials.

Front

What happens to the magnetic domains of an iron nail when it is near a magnet?

Back

The magnetic domains in the iron nail align with the magnetic field of the magnet, causing the nail to become magnetized.

Front

What are the two types of magnetic poles?

Back

The two types of magnetic poles are north and south poles.

Front

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

Back

Like poles repel each other; for example, north-north or south-south will push away from each other.

Front

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

Back

Opposite poles attract each other; for example, north-south will pull towards each other.

Front

What is the principle of magnetism?

Back

The principle of magnetism states that magnetic forces arise from the motion of electric charges.

Front

What is an example of a non-magnetic material?

Back

An example of a non-magnetic material is plastic.
