What is magnetic permeability?
Magnetic permeability refers to a material’s ability to absorb magnetic flux. It is defined as the ratio of the intensity of induced magnetization in the material to the intensity of the inducing magnetic force field that produced it. For the most effective magnetic shield attenuation performance, the higher the magnetic permeability, the better. CO-NETIC AA® magnetic shielding alloys are made to our exacting specifications and, most importantly, fabricated and final annealed using processes optimized to achieve the highest practicable magnetic permeability.
Some materials become magnetized when placed in a magnetic field. The ability of a material to become magnetized is called magnetic permeability. An example of this is rubbing a piece of iron with a magnet. The iron will become magnetized and have its own magnetic field. Substances with high permeability will become more easily magnetized than that of lower permeability. Some materials will lose magnetism when placed in a magnetic field or become only slightly magnetized. Therefore, magnetic permeability is the ratio that exists between the ability of a substance to gain or lose magnetism compared to the force of the magnetic field to which it is exposed. All substances, even water, have a degree of magnetic permeability. When a material is placed in a magnetic field it interacts with the field in one manner or another. The permeability of a substance describes the way the material responds and the effects of the field on said material. The more susceptible a material is to a magnetic
