In the arrangement shown in given Figure, there are two coils wound on a non-conducting cylindrical rod. Initially the key is not inserted. Then the key is inserted and later removed. Then,

• A. the deflection in the galvanometer remains zero throughout
• B. there is a momentary deflection in the galvanometer but it dies out shortly and there is no effect when the key is removed
• C. there are momentary galvanometer deflections that die out shortly; the deflections are in the same direction
• D. there are momentary galvanometer deflections that die out shortly; the deflections are in opposite directions

Answer 1

The correct option is D there are momentary galvanometer deflections that die out shortly; the deflections are in opposite directions
