Expert Answer:

Vacuum permeabilitypermeability of free space, or magnetic constant is an ideal, (baseline) physical constant, which is the value of magnetic permeability in a classical vacuum, and this type of vacuum is merely an abstraction from nature.
 When the permeability is that of the vacuum, denoted µ0 has an exact defined value:
µ0 = ×10−7 V·s/(A·m) ≈ 1.2566370614...×10−6 H·m−1 or N·A−2;

in the SI system of units, or using tesla·meter per ampere (T·m/A).
