How to model the magnetic field of the Earth

Have you tried the ELI 'Magnetic Earth'? This modelling activity is a useful prelude to an understanding of the magnetic field of the Earth, albeit due to a very different
magnetic source. It can assist in pupils’ understanding of the magnetic evidence for the movement of continents and for sea-floor spreading (when remanent magnetisation is preserved in rocks), and hence a major part of plate tectonic theory.
There are many activities you can use when teaching plate tectonics. They are listed in 'Teaching strategies' on our website.
