#1 The magnetic ckt Shown in figure I has dimensions Ac= 4x4cm le l = 0.06 cm = N = 600 turns 2 Assume the value of Hr = 6000 far ivan, Find the exciting current for Bc = 1.27 and the corresponding flux and flux linkages. Acc 4x4 cm Figure 1 Assume that all the care flux passes Straight down the air pap ( it means no fringing effect) #2. A cast steel dic electromagnet Shown in figure 2 has a cail of laaa turns on its central limb. Determine the current that the cail Should flux of 2.5mwb in the airpap. Carry to produce a meglect leakage. Dimensions are fillen in cm. The magnetisation curve for Cast Steel is as under Flux density in (lib/m) Amp-turns /metre 01.2 a.5 0.71.01.2 Path ACDE= 60cm Path EF-30cm 300 540 650/900/1150. A Figure 2 Path AGE=60cm 5cm Active Windo Go to Settings to mate: Path ACDE = AGE across the central path AE Flux density in either path is half of the central Path because flux divides into two equal Parts e paint A.
