A long solenoid having n turns per unit length and radius R carries a current I = Io sin cor. The displacement current density at a distance r from the axis with in solenoid is given by O ro 2c 7nIo sin (cot) ro 2 2c no sin (cot) $ 2c Io cos (cwt) $ wr 2c -nIo cos (at) & A long solenoid having n turns per unit length and radius R carries a current I = Io sin cor.
