### Understanding Magnetic Permeability - Ideal Magnet

1 天前  Magnetic Permeability is simply the ability of the material to form an internal magnetic field within itself under the influence of an applied magnetic field. Another way to understand it is that Permeability is the ability of a material to become magnetized when exposed to a magnetic field. But there's an even easier way to think of permeability.

### Magnetic Permeability - an overview ScienceDirect Topics

The magnetic susceptibility tensor plays a major role in the determination of the magnetic-polariton dispersion relation (just as its counterpart, the dielectric tensor, does for the non-magnetic plasmon-, phonon-, and exciton-polaritons). It describes the response of a magnetic crystal to the presence of an external magnetic field H →.

### Magnetic permeability [Encyclopedia Magnetica]

Magnetic permeability, μ (also written as mu) - a property of a given material or medium, quantifying its magnetic response of flux density B when subjected to magnetic field strength H. 1) 2) Magnetic permeability is proportional to the ratio B and H changes: μ = ΔB/ΔH. Several different kinds of permeability can be defined, depending on the character of changes in B and H.
