Frequently Asked Questions

What is the permittivity of free space actually?

Permittivity of free space is a constant of proportionality and it specifies the strength of electric force between electric charges in vacuum. It is represented by symbol εo . The value of permittivity of free space εo =8.854 × 10 -12 C 2 / (N m 2).

How the value of permitivity of free space is determined?

Permeability of free space. The permeability of free space, μ0, is a physical constant used often in electromagnetism. It is defined to have the exact value of 4π x 10 -7 N/A 2 ( newtons per ampere squared). It is connected to the energy stored in a magnetic field, see Hyperphysics for specific equations. ϵ 0 is the permittivity of free ...

What is the value of the permitivity of free space?

The permittivity of free space (a vacuum) is a physical constant equal to approximately 8.85 x 10 -12 farad per meter (F/m). It is symbolized o. In general, permittivity is symbolized and is a constant of proportionality that exists between electric displacement and electric field intensity in a given medium.

How was the permeability of free space derived?

Vacuum permeability is derived from production of a magnetic field by an electric current or by a moving electric charge and in all other formulas for magnetic-field production in a vacuum. The physical constant μ0, (pronounced "mu nought" or "mu zero") is commonly called the vacuum permeability, the permeability of free space, the ...
