IEVref: 121-11-56 ID: Language: en Status: Standard Term: magnetic field strength Synonym1: magnetizing field strength [Preferred] Synonym2: Synonym3: Symbol: H Definition: vector quantity obtained at a given point by subtracting the magnetization M from the magnetic flux density B divided by the magnetic constant μ0: $H=\frac{B}{{\mu }_{0}}-M$ NOTE 1 – In vacuum, the magnetic field strength is at all points equal to the magnetic flux density divided by the magnetic constant: $H=\frac{B}{{\mu }_{0}}$ NOTE 2 – The rotation of the magnetic field strength is the total current density Jt: rot H = Jt NOTE 3 – The magnetic flux density B is sometimes called “magnetic field”, risking confusion with the magnetic field strength H.
