hello PF. I have this exercise to do but I don't know how to do it.

Let's assume that the core in the figure is made up of ferromagnetic permeability material

μ = 2000 μ0. Let a = 4 cm, b = 2 cm, c = 3 cm the geometric dimensions, S = 8 cm2 the section

transversal, N1 = 100, N2 = 300 the number of turns of the two windings.

• Calculate the inductances of the two windings and the mutual inductances between

same;

• the position of the dots needed to identify the sign of the mutual is established

inductance;

• if two currents I1 = 3 A, I2 = 4 A flow in the two windings, both entering

on the side of the dots, calculate the overall flow concatenated with the two

windings.
