A square coil ABCD is placed in x–y plane with its centre at origin. A along straight wire, passing through origin, carries a current in negative z–direction. Current in the wire increases with time. The induced current in the coil is
(A) clockwise (B) anticlockwise (C) zero (D) alternating
using screw rule find direction of B, now B and area are perpendicular. B.A=0
so I=0
