Question

A square loop ABCD, carrying a current I₂, is placed near and coplanar with a long straight conductor  XY carrying a current I₁, as shown in figure. The net force on the loop will be

Answer 1

Correct option (d)

Explanation:

Force on arm AB due to current in conductor XY is

acting towards the wire in the plane of loop. Force on arm CD due to current in conductor XY is

 away from the wire in the plane of loop.

:. Net force on the loop = F₁  -  F₂
