In my class we were doing examples with a current carrying wire and if we moved with a speed v we would see length contraction. And because of this the moving line charge would go up in value and we would see an Electric field. And then we did the same for a solenoid but he said we need to factor in time dilation because it takes longer for the electron to go around one of the loops. But my question is why don't we factor in time dilation for a current carrying straight wire? My teacher said it didn't matter, but i don't see why. I am sure its simple tho.
