Hysteresis Loop Curve Electrical Academia
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. Thus the intensity of magnetization M at every stage lags behind the applied field H.

The B-H curve is usually used to describe the magnetization properties of such materials by characterizing the permeability , which is defined as: where and represent the magnetic flux density in tesla (T) and the magnetic field intensity in ampère per meter (A/m), respectively.

The B-H curve, also known as the magnetization curve, is an integral concept in the study of magnetism and magnetic materials. The 'B' in the B-H curve refers to magnetic flux density, while the 'H' stands for the magnetic field strength. Magnetic Flux Density (B)
A. BH Curve Understanding
Magnetic hysteresis Theoretical model of magnetization m against magnetic field h. Starting at the origin, the upward curve is the initial magnetization curve. The downward curve after saturation, along with the lower return curve, form the main loop. The intercepts hc and mrs are the coercivity and saturation remanence.
BH Curve Curve ElectricalWorkbook
Hysteresis Loop Definition 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.

Figure 1: DC magnetization curve In other words, for same increment in B, one has to apply more excitation in saturation region than in linear region. This is called as DC Magnetization Curve as both Band Hhave same sign. It is interesting to see what hapens when the external magnetic \excitation" is removed or reduced to zero.

Saturation is most clearly seen in the magnetization curve (also called BH curve or hysteresis curve) of a substance, as a bending to the right of the curve (see graph at right). As the H field increases, the B field approaches a maximum value asymptotically, the saturation level for the substance.
Manually Operated Lifter for Large, Thin Sheet Metal
Measuring B-H curves involves expensive equipment and requires considerable skill and experience, and published B-H curves are most often provided only graphically.. There are magnetization models used for modeling hysteresis and/or magnetostriction that can be reduced to just describe magnetic saturation, e.g. using a Langevin function and.

A BH curve, also known as a demagnetization curve, describes the magnetic qualities of a magnet more completely than a single number like Pull Force or Surface Field. It provides information about the strength of the magnet, how hard it is to demagnetize, and how a magnet's shape (or use in a magnetic circuit) affects matters.
