Question

A square loop ABCD carrying a current i, is placed near and coplanar with a long straight conductor XY carrying a current l, the net force on the loop will be

Answer 1

Correct option  (c)

Explanation:

Force on arm AB due to current in conductor -XY is

acting towards -17 in the plane of loop. 

Force on arm CD due to current in conductor XY is

acting away from -ill in the plane of loop. 

∴ Net force on the loop = F₁ - F₂
