Question: Consider the core shown in Figure , which has two coils of N turns, each connected so that the fluxes aid in the center leg.

Consider the core shown in Figure , which has two coils of N turns, each connected so that the fluxes aid in the center leg. Determine the value of N so that I = 2 A produces a flux density of 0.25 T in the gap. The gap and the core have square cross sections 2 cm on each side. Account for fringing by adding the gap length to the length of each side of the gap.
