Magnetic Hysteresis Loop including the B-H Curve
Then the B-H curve follows the path of a-b-c-d-e-f-a as the magnetising current flowing through the coil alternates between a positive and negative value such as the cycle of an AC voltage. This path is called a Magnetic Hysteresis Loop. The effect of magnetic hysteresis shows that the magnetisation process of a ferromagnetic core and therefore ...

6.2: B-H Curves
6.2.1 Measuring the B-H Loop. It is relatively easy to measure the axial magnetic flux density, B, in a specimen. It is only necessary to wind a few turns of wire closely around a specimen and to measure the emf developed across the coil terminals as an external field B 0 is changed with time, see Figure (6.2.7). The emf across the coil terminals is given by Faraday's law:
Magnetic Hysteresis Loop including the B-H Curve
A curve, or loop, plotted on B-H coordinates showing how the magnetization of a ferromagnetic material varies when subjected to a periodically reversing magnetic field, is known as Hysteresis Loop or Magnetization Curve. The term 'hysteresis' means to lag behind. In electrical terminology it is used to describe the lag between a change in ...

Plotting the B-H curve: Plot the B-H values on a graph with B on the vertical axis and H on the horizontal axis. Repeat the measurement and plotting process for different AC excitation frequencies and amplitudes. Calculation of Hysteresis Loss: The hysteresis loss can be calculated using the area enclosed by the B-H curve.

Mathematical Representation: The hysteresis loss (Ph) in a ferromagnetic material can be quantified using the formula: Ph = k * f * Bm * V. Ph is the hysteresis loss. k is a material-specific constant. f is the frequency of the alternating magnetic field. Bm is the maximum magnetic flux density. α is the Steinmetz exponent.
