I have recently studied about relativity being the reason for magnetism. The example given was about a magnetic field generated from current down a long wire. When two such wires with current in the same direction were parallel to each other there was an attractive force between them because from the reference frame of the electrons, the protons in the opposite wire were condensed, therefore a net attractive force.
Now my question: Would a cathode ray in a vacuum create a magnetic field like the wire does? I wonder this because in the cathode ray beam there are no corresponding protons like there are in the wire so there would be nothing to attract to...or what?
Thanks,
Chris
