Definition:

A magnet is an object that can pull certain metals towards It . It has a special invisible force called magnetic force.

Main Points

• A magnet has two poles: North pole (N) and South pole (S).

• Opposite poles attract (N + S).

• Same poles repel (N + N or S + S).

• Magnets attract only some materials, not everything.

• The area around a magnet where it works is called the magnetic field.

Interesting points:

• Even if you can’t see it, the magnetic field is always there.

• The Earth itself is a giant magnet!

• Your compass works because its needle is a tiny magnet.

• Fridge magnets stick because the door has steel inside.

Fun Fact:

A frog can actually float in a very strong magnetic field—because even living things have tiny magnetic particles!
