A core with three legs is shown in the figure below. The depth of the core is 5cm, and there are 100 turns on the leftmost leg. The relative permeability of the core can be assumed to be 2000 and constant. What flux exists in each of the three legs of the core? What is the magnetic field in each of the legs? Assume a 5percent increase in the effective area of the air gap due to fringing effects.
