What term refers to the specific conductivity of a material for a magnetic field?

Permeability refers to the specific conductivity of a material for a magnetic field. It is a measure of how easily a magnetic field can pass through a material. In magnetic materials, permeability quantifies the relationship between magnetic flux density and magnetic field strength, indicating how much magnetic field can be generated or maintained within the material under the influence of an external magnetic field.

When discussing magnetic properties, permeability plays a critical role, particularly in applications like transformers, inductors, and magnetic shielding. Materials with high permeability are often used in applications that require efficient magnetic field interactions because they allow for stronger magnetic fields to develop without requiring excessive energy input.

For clarity on the other terms: reluctance is the opposition to magnetic flux, inductance is related to how much voltage is induced in a circuit by a changing magnetic field, and magnetomotive force is a measure of the strength of a magnetic field created in a magnetic circuit. Each of these concepts is important in the realm of electromagnetism, but permeability specifically addresses the conductivity of materials in regard to magnetic fields.
