How Einstein saved magnet theory

Magnetism is one of the most bizarre of known classical physics phenomena, with many counter intuitive effects. Even weirder, when one uses Maxwell’s equations (the laws that describe electromagnetism) and traditional Galilean relativity, you can see that magnetism makes no sense at all. However, when one uses Einstein’s theory of relativity, it all makes perfect sense. In this video, Fermilab’s Dr. Don Lincoln helps sort it all out.
