A) Respectively clockwise and anticlockwise
B) Both clockwise
C) Both anticlockwise
D) Respectively anticlockwise and clockwise
Correct Answer: D
Solution :
When switch S is closed magnetic field lines passing through Q increases in the direction from right to left. So, according to Lenz?s law induced current in Q i.e. \[{{I}_{{{Q}_{1}}}}\] will flow in such a direction so that the magnetic field lines due to \[{{I}_{{{Q}_{2}}}}\]passes from left to right through Q. This is possible when \[{{I}_{{{Q}_{1}}}}\] flows in anticlockwise direction as seen by E. Opposite is the case when switch S is opened i.e. \[{{I}_{{{Q}_{2}}}}\]will be clockwise as seen by E.You need to login to perform this action.
