A closed magnetic circuit made from silicon steel consists of two sections, connected in series. One is of effective length 42 mm and csa 85 mm^2, and the other of length 17 mm and csa 65 mm². A 50 turn coil is wound on to the second section and carries a current of 0.4 A. Determine the flux density in the 17 mm length section if the relative permeability of the silicon iron under this condition is 3000.
