Two coils having 150 and 200 turn respectively are wound side by side on a closed iron circuit of section 150 cm² and the mean length of 300 cm. Determine the mutual inductance between the coils and the induced e.m.f. in the second coil if the current changes from zero to 10A in the first coil in 0.02 second. Relative permeability of iron – 2000, Permeability of free space = 4? x 10^- H/m.
