Question

two circular coils p and q are kept close to each other of which Koi p carries a current which will you observe in the galvanometer connected across to the 12 cube if current the quality is changed if both the coils are moved in the same direction with the same speed give reason to justify your answer in each case​

Answer 1

Answer:

Explanation:

(i) If current in coil P is changed, a current will be induced in coil Q. (ii) If both the coils are moved in the same direction with the same speed, their relative motion is zero. It is equivalent to not moving them at all. So because of this motion there won't be any change in Q

Answer 2

Answer:

(a) When current in P is changed, the field related with Q will differ causing an actuated current in Q.

(b) If both the loops are moved a similar way with same speed, there won't be any adjustment in the field related with Q. Thus no present will be actuated in Q
