Same as question 4 except the coil A is made to rotate about a vertical axis (Figure). No current flows in B if A is at rest. The current in coil A, when the current in B (at t = 0) is counterclockwise and the coil A is as shown at this instant, t = 0, is [NCERT Exemplar]
A. constant current clockwise.
B. varying current clockwise.
C. varying current counterclockwise.
D. constant current counterclockwise.
