1-7. A two legged core is shown in Figure P1-4. The winding on the left leg of the core (N₁) has 400 turns, and the winding on the right (N₂) has 300 turns. The coil are wound in the direction shown in the figure. If the dimensions are as shown, then what flux would be produced by currents i₁= 0.5A and i₂ = 0.75 A? Assume U_r= 1000 and constant.
