Magnetic Constant (μ0)

Definition

The magnetic constant (μ0), also known as permeability of free space, is an important physical constant representing the ability of vacuum to support magnetic fields. It relates the magnetic field strength to the electric current and is approximately equal to 4π × 10^(-7) T·m/A.
