The magnetizing force (H) vs the magnetic flux density (B) of a ferromagnetic material is represented by a magnetic hysteresis, also known as a hysteresis loop. This hysteresis loop so describes the route that a ferromagnetic material travels when a magnetizing force is applied and removed. In ferromagnetic materials, hysteresis is caused by two factors: rotation of the magnetization and changes in the size or number of magnetic domains. Magnetization fluctuates across a magnet in general, but not in sufficiently tiny magnets. When a ferromagnetic material is magnetized in one direction, it does not return to zero magnetization when the applied magnetizing field is released. Hysteresis is the lack of retractability of the magnetization curve, and it is related to the presence of magnetic domains in the material.a) The B-H curve of the specified data is: b) The magnetic field is the residual flux density when H=0, while remanent induction is the retention of magnetization in zero fields. It's the amount of flux density that remains when the external field goes from a high saturation magnetization to zero. Hence it is the value of B when H=0 A/m, therefore in this case remanent induction value is, H = 0.56 Wb/m2 c) The coercive field is the negative field that reduces magnetization from saturation to zero. Hence it is the external magnetic field H when B= 0 Wb/m2 Therefore, in this case, the coercive field is, H = -40,000 A/m
