I was just thinking about the simple concept that a moving electron produces a magnetic field at right angles to its travel... Now here's my question. Since we live in a relativistic universe, what is the charge moving with respect to in order to create the field? If we say the observer, then one is forced to conclude that the electron must always have a magnetic field around it since it is always going to be moving with respect to something... Where am I going wrong here?
