Magnetic Constant

The constant $\textit{Magentic Constant}$, also known as $\textit{Permeability of Vacuum}$, is a scalar constant $\mu_0$ such that, in a vacuum the product with the magnetic field vector, $\overrightarrow{H}$ is equal to the magnetic flux density vector, $\overrightarrow{B}$.

$\mu_0 = \frac{\overrightarrow{B}}{\overrightarrow{H}}$, where $\overrightarrow{B}$ is the B-Filed magnetic vector, and $\overrightarrow{H}$ is the H-Filed magnetic vector. The value of $\mu_0$ is $\approx 1.256637e-6\,H/M$.
