What is Permittivity?
Permittivity as the name suggests, must be something related to giving permission. Permittivity is the property of a matter or a medium to permit its own field to decrease the electrostatic force/electronic interaction between two charges. Permittivity can also be defined as the measure of electric polarizability of a dielectric, polarization of material causes induction of charges which in turn creates electric fields within the material, thus opposing the electricity between the original charged particles and also storing energy at the same time.
Definition of Permittivity
Permittivity is the property of the material or medium which measure the material’s ability to resist the formation of an electric field within it or to permit the passage of electric flux.
Permittivity Symbol: Electric Permittivity is denoted by the Greek symbol ε, pronounced as epsilon.
Unit of Permittivity: The SI unit of permittivity is Farad/meter (F/m).
Dimensional Formula of Permittivity: The dimensional formula of permittivity is [M1 L-3 T4 A2].
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.
