how magnetic fields protect us


Magnetism is a strange thing. Blobs of plasma containing different magnetic fields don't necessarily like to mix together. Remember - opposite poles of a magnet repel each other.


More important than any desktop toy, however, is the fact that the Earth's magnetic field repels and deflects the solar wind. It protects us with an invisible shield. This picture shows how...

Have a go and find out for yourself

Take two ring magnets and place them on a pole so that the same magnetic poles are facing each other. Imagine the lower magnet is the Earth's magnetic field and the upper magnet is the solar wind. Try making the solar wind fight against the Earth's magnetic field in its attempt to reach the Earth.
