In this activity, students investigate the pattern of magnetic fields on a fridge magnet. This will give them an idea of the principle behind scanning probe and magnetic force microscopes.
By the end of this activity, students should be able to:
- briefly explain how a magnetic force microscope works
- understand that the probe in a magnetic force microscope senses changes in the magnetic structure of the surface at the atomic level
- create an image of the magnetic structure of a fridge magnet.
