What are magnets? How does a magnet work? Fundamentally, magnets can be explained through quantum mechanics. This video will explain it in a bit easier fashion. Magnets basically boil down to the magnetic fields produced by electrons, due to the electrons spin. An electron's spin is an intrinsic property. When electrons of equal spin line up, they form larger magnets. In some rare earth metals, this can occur naturally. Most minerals and molecules have paired electrons with opposite spin, so the magnetic fields cancel out. Magnets are the driving factor of how motors work.
