  Consider an infinitely long wire carrying a current (t), with = constant. Find the current produced in the rectangular loop of wire ABCD if its resistance is R, Fig. 4(EP).17.

Answer:

                  In Fig. 4(EP).17, XY is infinitely long wire carrying current(t), such that = constant. At any distance r from the wire, strength of magnetic field, B (r) = It is directed out of the paper. Total magnetic flux linked with the rectangular loop                     ???(i)  where is self ? inductance of the loop Induced current,
