Problem
Two coaxial circular coils C₁ and C₂ are placed close to each other. The current in C₂ decreases with time and, as seen by an observer looking along the common axis, the current in C₂ is clockwise. The direction of the induced current in C₁, as viewed by the same observer, is
(a) anticlockwise
(b) no induced current (zero)
(c) clockwise
(d) first anticlockwise then clockwise
