turns to be 4 A: -) Find 4, l2, lz and l4 in meters. (4 points) Find cross-sectional area (in m²) in the four sections of the core. O Find the reluctances of each section (R1,R2, R3,R4) as defined in the equivalent circuit shown in the below figure. (4 points) O Find the total reluctance of the magnetic equivalent circuit Rtot. What is the magneto-motive force F produced by the coil in A.t? ) Calculate the total flux in the core and draw the direction of it in both figures. Calculate the magnetic flux density in the left and right columns (B1and B3). ( h) Calculate the magnetic flux intensity in the left and right columns (H, and H3).(2 points) Calculate the mmf drop across R1 and R3. (
