Question B2 continues...
Question B2 (continued) Flux Density, B. (T) 2.0 1.0 0.5 0 200 400 Magnetic Field Intensity, H, (A-t/m) Figure B2.c.b 600 800 1000 1200 1400 1600 1800 2000
(c) For the series magnetic circuit in Figure B2.c.a: i) Find the value of I needed to develop a magnetic flux of 3.0 mWb. Use the curve in [5%] Figure B2.c.b as necessary. ii) Using the current you calculated, find the magnetomotive force and the reluctance. [2%] Show the correct units.
