What is Permeability?
Permeability as the name suggests refers to easy of passing through. Permeability is the property of the matter which measure how easily it is allowing external magnetic field to pass through it or how much it gets magnetized when place in an external magnetic field. When an object in placed in an external magnetic field or when magnetic lines of forces are passed through a medium the dipoles in the medium get oriented in the material so as to facilitate the passage of the magnetic flux, this is called permeability. The high the permeability of the material the more magnetization it will show in presence of external magnetic field.
Definition of Permeability
Permeability is a property of matter to get magnetized when placed in an external magnetic field. It is the property of a material or the medium which reflects the easiness offered my the material or medium to pass magnetic flux through it when placed in an external electric field.
- Permeability Symbol: Permeability is denoted by the Greek letter μ, pronounced as mu.
- Unit of Permeability: The SI unit of permeability is Henry / meter (H/m).
- Dimensional Formula of Permeability: The dimensional formula of permeability is [M1L1T-2A-2].
Permittivity and Permeability
Permittivity and Permeability are two fundamental properties of materials that play a crucial role in the behavior of electromagnetic waves and related fields. Permittivity, represented by the symbol ε (epsilon), describes a material’s ability to permit the electric field to pass through it. Permittivity is a measure of how easily electric charges can be separated within the material in response to an applied electric field. On the other hand, Permeability, denoted as μ (mu), characterizes a material’s ability to allow magnetic fields to pass through it. Permeability represents how readily magnetic flux can propagate within the material when subjected to a magnetic field.
Together, Permittivity and Permeability determine the speed at which electromagnetic waves, such as light and radio waves, travel through a given medium. This article provides a brief description of both Permittivity and Permeability, other than that we will also discuss the key differences between Permittivity and Permeability.
