A wire of irregular shape in figure (A) and a circular loop of wire in figure (B) are placed in different uniform magnetic fields as shown in the figures below. In figure (A), the magnetic field is perpendicular into the plane. In figure (B), the magnetic field is perpendicular out of the plane.

The wire in figure (A) is turning into a circular loop and that in figure (B) into a narrow straight wire. The direction of induced current will be ___________.
Fill in the blank with the correct answer from the options given below.

Correct option is B

For fig (a) Since, the area of the loop is increasing with time, the flux through it will also increase. According to Lenz's law, the current induced will be such that it will oppose the increase in flux. Hence, induced current will be anti-clockwise.
Similarly For fig (b) Since, the area of the loop is decreasing with time, the flux through it will also decrease. According to Lenz's law, the current induced will be such that it will increase the flux. Hence, induced current will be anti-clockwise.
