. A square coil ABCD lying in x-y plane with it’s centre at origin

A long straight wire passing through origin carries a current i = 2t in negative z-direction. The induced current in the coil is


A. Clockwise

B. Anticlockwise    

C. Alternating

D. Zero



Best Answer

Ans: D

Sol: Magnetic lines are tangential to the coil as shown in figure. Thus net magnetic flux passing through the coil is always zero or the induced current will be zero.
