2. The B-H curve of a certain ferrous material is described by the following equation: B = (H/200)(0.2 + e-H/400) where H is in A/m and B is in T. If a magnetic circuit contains a 10-cm length of this material, as well as a 0.2-mm air gap, assume a uniform cross section of 3 cm2 and find: (a) the total mmf required to produce a flux of 360 µWb; (b) the flux if the applied mmf is 500 A.t.

A toroidal core of relative permeability ?? = 3000, has a mean radius R = 80 mm and a circular cross section with radius b = 25 mm. An airgap ?? = 3 mm exists, and a current I flows in a 500-turn winding to produce a magnetic flux of 10−5 Wb, as shown in Figure Q2(a). Neglecting flux leakage and using mean path length, find: 1. The reluctances of the air gap and the iron core 2. ?? and...
