A square loop 
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 [NEET 2016]
Text Solution
Verified by ExpertsD
Consider the given figure,
From the above figure, it can be seen that the direction of currents in a long straight conductor XY and arm AB of a square loop ABCD are in the same direction. So,
there exist a force of attraction between the two, which will be experienced by F BA as
In the case of XY and arm CD, the direction of currents are in the opposite direction. So, there exist a force of repulsion which will be experienced by CD as
Therefore, net force on the loop 
will be
