A square loop is symmetrically placed between two infinitely long current carrying wires in the same direction. Magnitude of currents in both the wires are same. Now, match the following two columns.

`{:(,"Column I",,"Colums II"),(A.,"Loop is moved towards right",p.,"Induced current in the loop is clockwise."),(B.,"Loop is moved towards left",q.,"Induced current in the loop is anti-clockwise."),(C.,"Wire-1 is moved towards left",r.,"Induced current in the loop is zero."),(D.,"Wire-2 is moved towards right",s.,"Induced current in the loop is non-zero."):}`

Answer

`(Ararrp,s;Brarrq,s;Crarrp,s;Drarrq,s)`

Explanation

In all of the cases, the induced current in the loop is non-zero. The direction of induced current can be determined by Lenz's law. When loop is moved towards right, then induced current in the loop is clockwise. When loop is moved towards left, then induced current in the loop is anti-clockwise.
