This core is quite popular in magnetic designs for power electronic circuits. Assume the relative permeability is 1500. All dimensions and turns are provided. To account for fringe effects around the air gaps, consider the effective area to be 5% larger than their physical size. The current in the middle core is 1.0 A. What is the flux in the left, center, and right legs of the core?
