Cut thin vertical and horizontal sections from a refrigerator magnet and then run these strips across the surface of the magnet. The strips act as probes that can be used to infer the arrangement of the magnetic poles on the magnet. The observations provide a simple analogy for the basic principle of scanning probe microscopy, which has allowed scientists to take “pictures” of atoms.
