Coercivity is usually referred to as the magnetic field required to demagnetize the material. Why is that? Because it tells us a lot about the magnetic hardness of the material in the same environment as its normal working environment.See all results for this questionWhat is coercivity force?Coercivity or Coercive Force. Coercivity is the resistance of a magnetic material to an opposing external magnetic field. There are two different kinds of Coercivity- Hcb and Hcj. The higher the Coercivity number, the higher the magnets resistance to the opposing field.See all results for this question
A high-permeability material is easily magnetised when exposed to a magnetic field, and the opposite goes for a low-permeability material. It is not to be confused with the degree to which the material gets magnetised. It rather is the ease with which the material gets magnetised. Coercivity is a lot lower for soft magnetic materials.What does coercivity mean?Simply put, Coercivity is the resistance of a magnetic material to changes in magnetization. Coercivity is usually referred to as the magnetic field required to demagnetize the material.See all results for this questionUnderstanding Coercivity - Ideal Magnet Solutions c45 steel permeability coercivityThe hysteresis loop of a soft magnetic material like silicon steel, for example, is a taller, thinner loop than that of a permanent magnet like NdFeB (Neodymium), which has more of a square hysteresis loop, as shown above in Figure 1.

Saturation Induction (Bs) The induced magnetization reaches a maximum, and changes little with large increases in magnetizing field strength. Also referred to as Bm, maximum induction.Magnetic Properties of Solids - HyperPhysics ConceptsHere the quantity K m is called the relative permeability, a quantity which measures the ratio of the internal magnetization to the applied magnetic field. If the material does not respond to the magnetic field by magnetizing, then the field in the material will be just the applied field and the relative permeability K m =1. A positive relative permeability greater than 1 implies that the c45 steel permeability coercivity
