A B
4.1.1 What is a magnetic field? (2)
4.1.2 List three properties of magnetic field lines. (3)
4.1.3 Draw the magnetic field pattern for this magnet. (2)

The bar magnet is now cut in half between A and B, and placed side by side
as shown below.

A c D B

4.1.4 What will be the nature of the force that the two magnets now exert on
each other? (Attractive or Repulsive)
Explain fully with reference to the polarity at C and D. (3)

4.2 The magnetic field lines of the Earth look very similar to the field lines of a bar
magnet. A compass is used to indicate direction. Like all magnetic fields, the
magnetic field of the Earth is caused by moving charges, in this case, charges
moving inside the liquid core of the Earth. The magnetosphere is very important
to life on Earth because it affects most of the solar winds. South Africa has a
permanent base in Antarctica where scientists study the magnetosphere and

aurorae.
4.2.1 Explain how a compass is used to indicate the direction of the Earth. (2)
4.2.2 What is a solar wind? (2)
4.2.3 How does the Earth’s magnetic field protect us from the solar winds? (2)
