The magnetization curve for material X under normaloperating conditions may be approximated by the expression
B = (H/160)(0.25 + e-H/320),

where H is an A/M and B is in T. If a magnetic circuit contains a 12 cm length of material X, as well asa 0.25 mm air gap, assume a uniform cross section of 2.5 cm2 and find the total mmf (Vm) to produce a flux of:
(a) 10μWb
(b) 100μWb
