Question

When the switch S is closed in the figure given below, the pointer of the galvanometer moves to the right.  

 

If S is kept closed, will the pointer:

(a) return to zero?
(b) stay over on the right?
(c) move to the left and stay there
(d) move to and fro until S is opened

Solution

return to zero
After some time, the magnetic field gets constant; this means that there is no relative change in the value of magnetic field. Therefore, the circuit will have zero induced current. 

  Is there an error in this question or solution?
