WebApr 8, 2024 · The correct answer is (B), area of I−H curve > area of B−H curve. Note: While finding the area under the closed hysteresis loop for both I-H and B-H curves, just taking normal integration will not give an accurate result. A student must take a path integral around the closed loop to get the area covered by it. WebIn air B = H and the B-H curve is a straight line with unit slope. The ratio B/H is the relative permeability of the core. It may be as low as five in some dust cores and as much as 5,000 in ferrite cores. The curve is now much steeper; the oscilloscope’s Y gain must be readjusted to create a reasonable display. FIGURE 1.
