**Introduction to Faraday's Law**

##### Question Details

A cylindrical iron rod of infinite length with cross-sectional area is oriented with its axis of symmetry coincident with the

*z*axis of a cylindrical coordinate system as shown in the figure. It has a magnetic field inside that varies according to . Find the theta component of the electric field at distance from the*z*axis, where is larger than the radius of the rod. (Shown in the figure)I have the answer... =

My professor did this in class and said that *hint* we should be familiar with this for an exam we have tomorrow. He worked through it very quickly, too quickly to hardly write down anything.

I just need to know the steps to get to the answer
