Definition - What does Magnetic Permeability mean?
Magnetic Permeability is the approach used to measure the relative strength of a magnetic field inside a material. It is also described as the property of a substance which is equal to the magnetic flux density established inside the material. Besides, permeability helps in classifying materials magnetically. For instance, a diamagnetic material like bismuth has permeability slightly less than 1 whereas a paramagnetic material like platinum has permeability slightly more than 1. However, ferromagnetic materials like iron do not have constant permeability.
Petropedia explains Magnetic Permeability
Magnetic Permeability is the approach which is used to calculate the ability of a material that supports the formation of the magnetic field within itself. Magnetic reluctivity is the reciprocal of Magnetic Permeability. It can be measured in Henry per meter. It is also related to the magnetic susceptibility that indicates the degree of magnetism. Generally, it acts as a constant of proportionality that exists between magnetic field intensity and magnetic induction. The effect is useful for designing chokes for audio frequencies, radio frequencies, and alternating current.
