 Permeability (electromagnetism)

Electromagnetic permeability relates magnetic flux density to magnetic field strength through $\mathbf{B}=\mu \mathbf{H}$ in an isotropic linear medium.

Permeability is a property of a material that indicates how well it can support the formation of a magnetic field within itself. In the context of electromagnetism, permeability is typically denoted by the symbol \( \mu \). It quantitatively describes the ability of a material to become magnetized when exposed to an external magnetic field and is central to understanding magnetic materials' behavior.
