Problem
The current in a large circular coil lying in the plane of the page is increasing in the anticlockwise sense. A smaller, coaxial loop is placed inside it in the same plane. What is the direction of the induced current in the smaller loop while the current in the large coil is rising?
(a) Anticlockwise
(b) No current is induced
(c) Clockwise
(d) Direction keeps alternating every half cycle
