This workshop explains the magnetism of rocks and the basics of geomagnetism.


Educational content : magnetism, magnets, magnetic minerals in the rocks, geomatism and its applications, geophysical prospection using magnetism and its application.

We have posters (in French) :

  • Magnetism and magnets : what is a magnetic field ?
  • Magnetic prospection : How magnetism can help understand the ground ?
  • Geomagnetism : what is the Earth magnetic field ?

Several models for demonstration, roughly divided into 6 sections to conduct the presentation :

  • Magnetic fishing
  • The two poles of a magnet
  • The field lines
  • Magnetic prospection : the great model
  • Magnetism in the rocks
  • Geomagnetism : the Earth’s magnet

The workshop "teacher’s guide" is available (in French) on demand before or after the presentation.
