Question 9: The iron core is equipped with an excitation winding, which is not shown in the diagram. The dimensions of the iron core are a=3 cm, b=2cm, c=4cm, g=0.2cm, w=10cm, h=11cm. The magnetic circuit operational data are: Bgap=0.8T, Im=8A, µo = 4rx10-7Wb/A-t-m. The B-H curve is given. What are the flux and flux density in different sections? What are the magnetic field intensities in different sections? What is the number of turns in order to maintain the flux?
