Question 2 In the magnetic circuit detailed in below Figure with all dimensions in mm, calculate the required current to be passed in the coil having 200 turns in order to establish a flux density of 0.8 T in the center leg. The B-H curve of the material is given as shown in the figure. Permeability of air may be taken as, μo = 4 × 10-7 H/m B in Tesla 40 + 2.4 2.0 1.6 1.2 0.8 0.4 60 60 200 40 60 200 60 1000 2000 3000 H (AT/m) 500
