(a) Find E(R,t), the electromotive force (EMF) around a loop that is at distance R from the z axis, where R is restricted to the region outside the iron rod as shown. Take the direction shown in the figure as positive. (b) Due to the cylindrical symmetry of this problem, the induced electric field E→(R,t) can depend only on the distance R from the z axis, where R is restricted to the region outside the iron rod. Find this field.
