A magnetic core with an air gap is shown below. For a relative permeability is 3500, and the space free permeability is 4x10-7 H/m. Find the reluctance of the left leg and the top side of the core. Ignore the gap in your calculations. 10 cm 20 cm 5 cm 5 cm N 40 cm 04 0.1 cm gap core depth = 10 cm 5 cm
