Magnets 01

Magnets in KS3 Science explain forces, attraction, and repulsion. They show how magnetic fields work and why compasses point north using Earth’s magnetic pull.

Fascinating Fact:

Magnetite is a naturally magnetic rock that can even make a compass needle move.

In KS3 Science, pupils study magnets and magnetic fields. They learn how magnets attract or repel, how compasses work, and why magnets are vital in motors and electronics.

  • Magnetic Field: The invisible area around a magnet where magnetic forces act.
  • Poles: The two ends of a magnet, called north and south, where the force is strongest.
  • Compass: A tool with a magnetic needle that shows direction using Earth’s magnetic field.
What are the two poles of a magnet called?

The two poles of a magnet are called the north pole and the south pole. Opposite poles attract each other, while like poles repel.

How does a compass use magnetism?

A compass works because its needle is a small magnet. It lines up with Earth’s magnetic field, always pointing north and south.

What materials are magnetic in KS3 Science?

Only certain metals are magnetic, such as iron, cobalt, and nickel. Alloys like steel, which contain iron, are also magnetic.

1 .
If a north and a south pole are near each other ..…..
Nothing will happen
They will attract
They will be demagnetised
They will repel
Opposite poles attract, similar poles repel
2 .
When a magnet is suspended ..…..
It will line up in E-W direction
It will line up in N-S direction
It will not move
It will point up-down
It lines up with the magnetic field of the Earth
3 .
The ends of a bar magnet are called .......
East and west poles
North and south poles
North poles
South poles
Magnetic force is strongest at the poles
4 .
To show the magnetic area around a magnet we use .......
Aluminium powder
Copper filings
Iron filings
Pepper
The other materials are not affected by a magnetic field
5 .
The stronger a magnet .......
The harder the metal
The larger the magnetic force
The smaller the magnetic force
The softer the metal
Magnetic force acts at a distance
6 .
The area around a magnet is called a .......
Magnetic area
Magnetic field
Magnetic force
Magnetic space
All magnets are entirely surrounded by their magnetic field
7 .
If two north poles are near each other .…...
Nothing will happen
They will attract
They will be demagnetised
They will repel
Maglev (stands for magnetic levitation) trains use this idea to lift them off the ground
8 .
A magnetised piece of steel can be used in .......
A compass
A computer mouse
A remote control
A watch
A compass points to magnetic north and not geographical north, so, when using a compass for navigation, the difference in location between the two poles has to be taken into consideration
9 .
Which one of the following groups of metals are attracted to a magnet?
Copper, nickel, steel
Gold, nickel, iron
Gold, steel, copper
Steel, iron, nickel
Steel contains mainly the element iron
10 .
Which of the following metals is NOT magnetic?
Cobalt
Copper
Iron
Nickel
Copper objects will therefore not be attracted to a magnet
