WebConsider the B-H curve of a transformer in the figure below. Operation at or close to knee point results in increased core flux density. This translates to having a lesser core cross-section area for a given flux level requirement. Hence, there is saving core material. WebB = H (5) More details on analysis of magnetic circuits can be found in chapter 2 in [1]. Let us consider materials used in the laminations of transformers. They are called ferromagnetic materials. A piece of ferromagnetic material is composed of several \domains". In each domain, magnetic moments of all atoms are aligned in one direction.

The graph intensity of magnetization (M) vs. magnetizing field (H) gives a closed curve called M-H loop. Consider the portion AB of the curve given below. The intensity of magnetization M does not become zero when the magnetizing field H is reduced to zero.
WebIn practice real magnetic materials have a B-H curve as follows: The curve shown above is termed the 'hysteresis' loop of the material, and it represents the true B-H response of the … 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.
