Gabee, Jostpurr, Daniel -- Thanks for the great responses! fb

But the speed of the electrons is very slow... Thanks Daniel. This is my understanding -- that a magnetic field is a relativistic view of an electric field -- and that the single, unified, underlying process is that of photon exchange between charges. So a magnetic field "is just really an...

I'm a newbie, so please correct me if this is not a good post. Question: 1 The absolute speed of current-carrying electrons of a steady current in a wire are very slow, with respect to the wire. 2 So how does the magnetic field arise from the relativistic imbalance between the moving...
