Ok. I am having trouble identifing the saturatoin field on the Hysteresis Loop. How do I find it?Also the initial and maximum relative permeability. Is the maximum relative permeability infinte?
The "saturation field" is the field at which the curve just about levels out.drcrabs said:Ok. I am having trouble identifing the saturatoin field on the Hysteresis Loop. How do I find it?Also the initial and maximum relative permeability. Is the maximum relative permeability infinte?
A magnetisation curve is a graphical representation of the relationship between the magnetic field strength and the magnetic flux density of a ferromagnetic material. It shows how the material responds to changes in the magnetic field, and can be used to determine the material's magnetic properties.
A hysteresis loop is a graphical representation of the relationship between the magnetic field strength and the magnetic flux density of a ferromagnetic material, as the magnetic field is cycled between positive and negative values. It shows the lag between the changes in the magnetic field and the material's response, and can be used to study the material's magnetic behavior.
Hysteresis in a magnetisation curve is caused by the rearrangement of magnetic domains within the material. As the magnetic field changes, the domains align themselves in different directions, leading to a lag in the material's response. This lag is known as hysteresis and is a characteristic of ferromagnetic materials.
The shape of a hysteresis loop can vary depending on the type of material. Soft magnetic materials, such as iron, have a narrow hysteresis loop, indicating that they can quickly respond to changes in the magnetic field. Hard magnetic materials, like neodymium, have a wider hysteresis loop, showing that they require a stronger magnetic field to change their magnetic state. Different materials also have different coercivity, which affects the shape of the hysteresis loop.
Understanding the magnetisation curve and hysteresis loop can help in the design of magnetic devices, such as motors, transformers, and magnetic storage media. It can also aid in material characterization and quality control for ferromagnetic materials used in various industries, including electronics, automotive, and energy.
