Magnetic Permeability

Magnetic permeability is a measure of how easily a material can become magnetized or allow magnetic field lines to pass through it. In the context of magnetostatics, it indicates how a material responds to an external magnetic field. High permeability means the material can store magnetic energy effectively and enhance the magnetic field within it, while low permeability indicates weaker interaction with the field. Different materials, like iron or air, have varying permeabilities, influencing their roles in devices such as transformers, inductors, and magnetic shields.
