The unit for the magnetic field strength H can be derived from its relationship to the magnetic field B, B=μH. Since the unit of magnetic permeability μ is N/A 2, then the unit for the magnetic field strength is: T/(N/A 2) = (N/Am)/(N/A 2) = A/m. An older unit for magnetic field strength is the oersted: 1 A/m = 0.01257 oersted. Index
