The correct answer is D

Current carrying wire produces magnetic field, but direction of magnetic field on the given points X and Y are different. 
 
This is found by right hand thumb rule. So magnetic compasses on X and Yexperience magnetic force of same magnitude but in opposite directions. Hence, the needles will deflect in opposite directions.

Three closed similar coils P, Q and R are placed such that their planes are parallel. In the coil P and R, current of same magnitude flows as shown in the figure. Coils Q and R are static while coil P is moved with a uniform speed towards Q, then


A Clockwise current will be induced in coil Q, as seen by eye
B Anti-clockwise current will be induced in coil Q, as seen by eye.
C No current will flow in coil Q
D Current induced in coil Q will be equal to P and R, but in opposite direction, hence net current in Q will be zero.

The correct answer is B

Coil P is moved with a uniform speed towards Q while R is static. Due to the current in P, magnetic field is from right to left. When P is moved towards Q, magnetic lines passing through Q (from right to left) will increase, i.e., magnetic flux passing through Q will increase. Therefore, current will be induced in Q. The induced current will have such a direction that it gives a magnetic field opposite to that passing through Q due to current in P. Thus, anticlockwise current will be induced in coil Q, opposite to the direction of current in coil P.
