I was told that fields don't travel. So if i have a wire with initially no current running and then i flip a switch to start some current, and I am at a distance x from the wire. Is the time lag from the wire at the speed of light before i feel the B field from the wire? Does the B field propagate out from the wire at the speed of light?
Any input will be much appreciated.
