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 the segments 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) Cross$\ \bigotimes$ magnetic field passing from the closed loop is increasing. Therefore, from Lenz’s law induced current will produce dot $\bigodot$ magnetic field. Hence, induced current is anticlockwise.
