Magnetism Deduced from Relativity If experimentation is not your thing, the presence of magnetism can be deduced from the concepts of relativity. Magnetism and Relativity The existence of magnetism allowed for the derivation of special relativity . In fact, Einstein's famous 1905 paper was entitled "On the Electrodynamics of Moving Bodies". The strange phenomena that only appeared with moving charges allowed Einstein to show that magnetism was simply electric interactions in different reference frames, and to use this obsevation to prove the existence of time dilation, length contraction, and all the other mind-boggling concepts that accompany relativity. Since empirical derivation often fails to bring full understanding of a topic, a popular way of teaching magnetism is to derive it from relativity, reversing Einstein's logic. Starting with relativity and electrostatic theory, one may derive quite precisely the experimentally calculated properties of magnetism. The mathematical derivation is quite complicated, but we can give a
