C permittivity permeability
WebExpressions for the electric and magnetic fields in free space contain the electric permittivity ε 0 and magnetic permeability μ 0 of free space. As indicated in the section on electric and magnetic constants , these two quantities are not independent but are related to "c", the speed of light and other electromagnetic waves . WebSep 22, 2024 · There are two physical quantities namely Permittivity and Permeability that play a vital role in the field electrical engineering. Permittivity is related to electrostatics and it is the measure of electrical polarization of a dielectric material when it is placed in an external electric field.
