Consider a non-conducting ring with positive charge fixed on uniformly . This arrangement is rotated about the axis of the ring with an uniform angular velocity.
I understand that this arrangement will produce both an electric field and an magnetic field. I have further found out somewhere that the electric field will not be "time-independent electrostatic out of system".
I think that at any time '$t$', the charge distribution though moving will be the same as that when it was at rest or at any other time. Hence the electric field produced should be same at any time '$t$'.
What is the flaw in my understanding?
