The Permeability of Free Space, μ0, is also known as Permeability of a Vacuum and sometimes as the Magnetic Constant.  This constant is used to measure the amount resistance to forming a magnetic field in a classical vacuum.  This constant is used in a number of equations related to magnetic field density and its relationships to magnetic flux density.

Notes

The Permeability of Free Space is defined as 4πx10-7VsAm, which is approximately:

    1.2566370614359173E-6 VsAm or
     1.2566370614359173E-6 Hm or
     1.2566370614359173E-6 NA2 or
     1.2566370614359173E-6 TMA or
     1.2566370614359173E-6 WbAm

This is an exactly known constant since it is the product of a precise value with a precisely known number, Pi.
