The electromagnetic system shown in Figure Q2 consists of a ferromagnetic steel core material with a constant relative permeability of 1600 up to a flux density of 1.5 T. The coil has 2000 turns. Leakage flux and fringing at the air gaps is negligible. (i) Develop a magnetic equivalent circuit for this system and hence determine the coil current required to produce an air gap flux density of 1.1 T when the air gap length is (16 marks) 2 mm. (ii) Find the force on the armature for the conditions in (i). (4 marks) 20 100 15 15 30 15 15 Figure Q2 30 80 484 20
