A square loop is placed near a long straight current carrying wire as shown. Match the following two columns.
Column I | Column II | ||
(A) | If current is increased | (I) | Induced current in loop is clockwise |
(B) | If current is decreased | (II) | induced current in loop is anti-clockwise |
(C) | If loop is moved away from the wire | (III) | wire will attract the loop |
(D) | If loop is moved towards the wire | (IV) | wire will repel the loop |

If current is increased, 
magnetic field passing through loop will increase. So, induced current will produce 
magnetic field. Hence, induced current is anticlockwise.
Now, i and I currents in PQ are in opposite directions. Hence, they will repel each other.
