A rectangular loop of sides `27cmxx12cm` carries a current of `12A`. It is placed with its longer side parallel to the long straight conductor `3*0cm` apart and carrying a current of `20A`. Figure. (i) Find the net force on the loop (ii) What will be the net force on the loop if the current in the loop be reversed?  img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/PR_XII_V01_C03_E01_155_Q01.png" width="80%"
