Modelling ancient and modern magnetic fields

'Human magnets! Modelling ancient and modern magnetic fields, using your pupils'. In this Earthlearningidea, pupils use their own bodies to model the magnetisation induced in magnetite mineral particles by the Earth’s field of today: also the magnetic evidence within ancient rocks for ‘continental drift’.

The activity can be used to aid the understanding of remanent magnetisation in rocks. This in turn provides evidence of past magnetic fields of the Earth and is of great value in demonstrating the former latitudes of the continents, before their plate tectonic movement.

Many more activities about magnetism can be found on the website.
