    Abstract - (Show below) - (Hide below)

    Applies to all ferromagnetic materials and particularly aimed at the measurement of the magnetic dipole moment of permanent magnet (magnetically hard) materials and the measurement of the specific saturation magnetic polarization of cemented carbide materials having a ferromagnetic binder.
