E A long, straight wire carries a 25 A current along its length. The wire passes through the center of a circular ring, as shown. A time-varying electric field passes through the ring and is parallel to the wire. The electric field is also uniform across the ring. The magnetic field everywhere along and through the ring is zero. If the ring's diameter is 4.0 cm., how much does the strength of the electric field change after 10.0 s?
