What makes Magnets Magnetic? All matter is made up of atoms. Atoms in turn, are made up of protons, electrons and neutrons. In most materials almost all the electrons form pairs, with the magnetism from the two paired electrons exactly cancelling. This makes such materials non-magnetic. What...
Physicists have some understanding of how magnets function. However, some phenomena that underlie magnetism continue to elude scientific explanation. Exactly how do magnets work? Large-scale magnetism, like the kind observed in bar magnets, results from magnetic fields that naturally radiate from the ...
