Question

A square loop 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:, 2 μ 0 I i 3 π, μ 0 I i 2 π, 2 μ 0 I i L 3 π, μ 0 I i L 2 π

F 1 = μ 0 I i L 2 π L 2 = μ 0 I i π F 2 = μ 0 I i L 2 π 3 L 2 = μ 0 I i 3 π ∴ F n e t = F 1 - F 2 F n e t = 2 3 μ 0 I i π
