Q.
The figure shows certain wire segments joined together to form a coplanar loop. The loop is placed in a perpendicular magnetic field in the direction going into the plane of the figure. The magnitude of the field increases with time. $I_{1}$ and $I_{2}$ are the currents in segment ab and cd. Then,
A) $I_{1} > I_{2}$
B) $I_{1} < I_{2}$
C) $I_{1}$ is in the direction ba and $I_{2}$ is in the direction cd
D) $I_{1}$ is in the direction ab and $I_{2}$ is in the direction dc
Explanation
(d) Due to decrease in crosses ($\times$), induced current in outer loop is anticlockwise, $i.e.,$ from d to c and clockwise in inner loop $i.e.,$ from $a \rightarrow b$
