Problem
A long solenoid carries a current that is increasing in such a way that the face of the solenoid toward an observer behaves as a north pole. A circular conducting loop is coaxially wrapped around the solenoid. What is the direction of the current induced in the loop as seen by the observer?
(a) Clockwise
(b) Anticlockwise
(c) Alternates periodically
(d) No current is induced
