Key Concepts

Relative Permeability

Relative permeability is a dimensionless quantity that compares the magnetic permeability of a material to that of free space (vacuum permeability). It reflects how a material responds to an external magnetic field, with values typically around one for non-magnetic materials and usually less than one for diamagnetic substances.

Diamagnetism

Diamagnetism is a form of magnetism exhibited by materials that create an induced magnetic field in a direction opposite to an externally applied magnetic field, resulting in a relative permeability that is slightly less than one. This characteristic response arises due to the orbital motion of electrons within the material and leads to a weak repulsion from the magnetic field.

Relative Permittivity

Relative permittivity is a dimensionless measure of how much a material can concentrate electric flux compared to a vacuum. It indicates how the material responds to an external electric field by polarizing, and its value is typically greater than or equal to one in most conventional materials, depending on the material's composition and structure.
