So does a wire actually have a magnetic north and south pole? I know a coil of wire will form one but a straight wire will only attract another wire if the other wire's current is going in the opposite direction and repel if in the same direction. I have looked for images and they always just show a magnetic field circling the wire with no apparent end like a bar magnet or coil of wire has. 2nd. Does a electron in motion have a magnetic north or south?
