The electric field from a ball-bearing carrying a static electric charge, is presumeably spherical. What happens to that field shape if I spin the ball? Surely at some distance,
$d > c/w $, ( where c is the speed of light and w is the angular velocity )
from the ball-bearing, the field would have to be travelling in a circle faster than the speed of light, and that's not possible! So does the field come to a stop at this distance? does it gradually 'spiral' as it approaches d or what?
