Question

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 increase 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

Answer 1

The correct option is D

$I_1$ is in the direction ab and $I_2$ is in the direction dc

The direction of induced current will be in the anti-clockwise direction in the outer loop and clockwise in the inner one as the flux through the loop is increasing due to an increase in the magnetic field.
