A square conducting loop is placed in the neighbourhood of a coplaner

1.	A square conducting loop is placed in the neighbourhood of a coplaner long straight wire carrying a current i. A. if `(di)/(dt)=0`, no current is induced in the loopB. if `(di)/(dt)gt0` , current in the loop is clockwise.C. if `(di)/(dt)lt0` , current in the loop is anticlockwise.D. if `(di)/(dt)gt0` , current in the loop is anticlockwise.
Answer» Correct Answer - A::D If `(di)/(dt)=0`, it means current is constant, its flux through loop with remain constant. Hence no emf is induced. If `(di)/(dt)gt0`, current increases so flux increates in loop in inward direction, so induced current should be anticlockwise which produces flux in outward direction.
