A straight wire 5m long is placed parallel to an infinitely long straight wire carrying current 5A. The distance between the two wires is 10 cm and the 5m long wire is carrying current 2A. The force on the shorter wire is :

Figure shows a square conducting frame and a long wire-both lying in the same plane. The side length of the square loop is ‘a’ and it is at a distance ‘a’ from the long wire which is having a steady current I_(0) . The inductance and resistance of the square loop are L and R respectively. The loop is turned by 180° about its side AB so as to bring it to final position ABC'D' at rest. Calculate the net charge that flow past a side of the loop.

A long straight wire carries a current of 10.05 A to the right. A circular loop of wire lies below the long straight wire, as shown in the following figure. The current in the long straight wire decreases to zero in a time of 4.652 s. What direction does the induced current flow around the circular loop of wire?

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 :
