Consider the magnetic circuit shown below. The primary coil has N1=400 turns, and the secondary coil has N2=800 turms. The total length of the core (shown in red) is 5 cm. The core has a uniform cross section 2 cm2 , magnetic permeability 900. Calculate the total inductance between terminals a and b, if the coils are connected as shown below. Assume that there is no flux leakage from the core. N1 N2
