A paradox?....In STR. A thought experiment; This could take place in a hallway or in space, whichever you prefer. Consider an electron somewhere around the center of your monitor. Now have an observer A at the right of your screen closing the distance between the electron and himself in a uniform manner. The STR allows this observer to claim to be at rest and that the electron is moving toward him and emitting a rotating magnetic field in the correct manner if he could see it. At the same time have observer B coming from the left of your monitor closing the distance between the electron and himself. Observer B is moving in a uniform manner. Observer B can also claim to be at rest and that the electron is moving toward him emitting a rotating magnetic field in the correct manner. The electron would have to emit two fields rotating in opposite directions to satisfy each observer. Because the electron has a rotating magnetic field, does it have to be placed in a preferred reference frame? How does the electron know which way it is moving in order to emit the proper field. Does the electron have to be accelerating in order to produce a rotating magnetic field? I sent this "paradox' to two physicists. They didn't reply so something must be wrong with the way I phrased it. It was unsolicited so was probably trashed. Any ideas?
