Measurement of Magnetic Dipole Moment in Ferromagnetic Materials according to IEC 60404-14 Ed. 1.0 b:2002

Relevant to all ferromagnetic supplies. It’s significantly aimed on the measurement of the magnetic dipole second of everlasting magnet (magnetically exhausting) supplies and the measurement of the particular saturation magnetic polarization of cemented carbide supplies having a ferromagnetic binder. To explain the final ideas of the dedication of the magnetic dipole second of a ferromagnetic materials specimen utilizing a detection coil in an open magnetic circuit. By together with a method of magnetizing the fabric to saturation, the saturation magnetic dipole second will also be decided. As well as, the common magnetic polarization of a check specimen might be derived from the measurement of its magnetic dipole second and quantity. The calibration of magnetic second coil methods and the measurement of the magnetic dipole second of feebly magnetic supplies will also be decided utilizing this methodology. Measurements are usually carried out at room temperature however measurements at different temperatures might be performed by heating or cooling the amount occupied by the check specimen inside the detection coil. The measurement of remanence, coercivity, most power product and different parameters might be made in a closed magnetic circuit as described in IEC 60404-4 and IEC 60404-5. Measurement of the coercivity HcJ of soppy and semi-hard supplies will also be carried out in an open circuit as described in IEC 60404-7.
