QN1 A 30 cm long circular iron rod is bent
into circular ring and 600 turns of windings are wound on it. The diameter of
the rod is 20mm and relative permeability of the iron is 4000. A time varying
current i = 5 sin 314.16t is passed through the winding. Calculate the
inductance of the coil and average value of emf induced in the coil.
