Teaching Minds-On Experiments on Electromagnetism in Secondary Schools Permanent magnets Atomic force microscope model (reference to a practical application)
In
the experiment shown below, we present a model of atomic force
microscope. A thin metal belt (used in anti-robbery shop systems) is
moving slow and attracting to the blue "paper" three times.
There are placed three magnets under the paper and they attract real
the metal belt. In the same way works atomic force microscope.
