A C-shape core made of sheet steel, has a cross sectional area of 0.2 x 103 m. The average length of air gap is 0.008 m and the average length of the sheet steel is 0.3 m. The flux in the magnetic circuit, is 0.24 mWb and the coil turns, N is 600. Neglect fringing and the B-H curve of the core is shown below. (Permeability of free space p = 4x x 10-7 Hm-1) i ii. 111. Draw the equivalent Ampere's Circuital Law model. Determine the current to establish the required flux. Explain what the purpose of neglecting fringing.
