The figure shows certain wire segments joined together to form a coplaner 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,

Options

A. `(I_1)gt(I_2)`
B. `(I_1)lt(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

D

Explanation

the magnetic field is increasing in the downward direction. Therefore, according to Lenz's law the current `(I_1)` will flow in the direction ab and `(I_2)` in the direction dc.
