A two-legged core is shown in Figure. The winding on the left leg of the core (N1) has 400 turns, and the winding on the right (N2) has 300 turns. The coils are wound in the directions shown in the figure.
If the dimension are as shown, then what flux would be produced by currents i1 =0.5 A and i2 =0.75 A?
Assume u = 1000 and constant.
