If the magnetising field on a ferromagnetic material is increased, its permeability is

A magnetizing field of 360A//m produces a magnetic flux density B = 0.6T in a ferromagnetic material. What is its permeability in TmA^-1 ?

A magnetising field of 360 Am^(-1) produces a magnetic flud density (B) =0.6 T in a ferromagnetic material what is its permeability in TmA^(-1) ?

When temperature of a ferromagnetic material is increased by 10%, what is the percentage change in its magnetic susceptibility?

If the permeability of a ferromagnetic material is independent of the magnetic field? If not is it more for lower or higher fields?

When a small magnetising field H is applied to a magnetic material the intensity of magnetisation (I) is proportional to:

When a ferromagnetic material is heated above its Curie temperature , the material

When a ferromagnetic material is heated above its Curie temperature , the material

The basic magnetization curve for a ferromagnetic material is shown in figure. Then, the value of relative permeability is highest for the point
