coplanar with a long straight conductor XY carrying a
current I, the net force on the loop will be : [2016]
(a) 2μ₀Ii/3π (b) μ₀Ii/2π
(c) 2μ₀IiL/3π (d) μ₀IiL/2π

Answer 1

Explanation:

A square loop of ABCD carrying a current i, is placed near and coplanar with a long straight conductor XY carrying a current I, the net force on the loop will be. D. ... In the case of XY and arm CD, the direction of currents are in the opposite direction.
