A rectangular wire loop of width a is suspended from the insulated pan of a spring balance as shown in figure. A current i exists in the anticlockwise direction in the loop. A magnetic field B exists in the lower region(Perpendicular to plane of loop in inward direction). Find the change in the tension of the spring if the current in the loop is reversed?Sir, There is no net magnetic force exerted on a closed loop carrying current in a uniform magnetic field, But here in H.c.verma, Answer is given 2Bia?Sir, It is the Question Of H.C.Verma, Pg no.231 Volume2Loop is a square of side measuring "a".
