BH Curve

The BH curve, also known as the magnetization curve, shows how a magnetic material responds to an external magnetic field. It plots the magnetic flux density (B) against the magnetic field strength (H). As H increases, B initially rises gradually, then more rapidly, until it reaches a point of saturation where further increases in H produce minimal effect. This curve helps us understand a material's magnetic properties, such as how easily it can be magnetized and how it behaves in devices like transformers and motors, illustrating the relationship between the applied magnetic field and the resulting magnetic flux within the material.
