Leo panicked. Then he breathed. He started drawing the magnetic equivalent circuit: three reluctances in parallel, but with the center leg’s air gap dominating. He wrote Kirchhoff’s flux law (Φ1 = Φ2 + Φ3). He wrote the magnetomotive force (MMF) loop equations. Then he hit the wall: the B-H curve meant μ wasn’t constant. magnetic circuits problems and solutions pdf
Answer: I = 0.638 A.
The magnetomotive force (MMF) is given by:
