Question

The permeability of the ferromagnetic substance is​

Answer 1

where the permeability, µ, is a scalar if the medium is isotropic or a second rank tensor for an anisotropic medium. A ferromagnetic material, such as iron, does not have a constant relative permeability. As the magnetizing field increases, the relative permeability increases, reaches a maximum, and then decreases.

Answer 2

Answer:

A paramagnetic material has a constant relative permeability slightly more than 1. When a paramagnetic material, such as platinum, is placed in a magnetic field, it becomes slightly magnetized in the direction of the external field. A ferromagnetic material, such as iron, does not have a constant relative permeability.

the permeability (μ) of a ferromagnetic substance is

(a) μ > 1

(b) μ = 1

(c) μ < 1

(d) μ
