Question
A straight right-circular cylindrical solenoid of radius R and length L> R is wound wvith n turns of wire per unit length. The current / in the windings is rising slowly. (a) Calculate the electric field (magnitude and direction) at a distance r<R from the axis inside the solenoid and well away from its end. (b) Calculate the electric field (magnitude and direction) at a distance r from the axis such that R<r<L and not too far from the midpoint. (c) Briefly discuss how your results might be changed if the current rises very rapidly.
