TriM – Measurement of the Magnetic Moment
In most applications permanent magnets shall provide a specific magnetic flux (e. g. in electric machines) or a specific spatial field distribution (e. g. sensors). The determing factor is the magnetic moment Mm and not only the remanence induction of the magnet.
- Precise rating of series deliveries by the calculation of the working point polarization Jr’ from the volume
- Measurement of magnets with bended or untreated pole faces or broken edges (Mm is calculated from the volume via weight and specific density)
- Calibration of Permagraph measurements of high energy density magnets (SmCo, NdFeB)
- Precise calculation of the remanence induction Br with the permanent permeability µp
- Calculation of the grade of saturation after magnetization (Has the magnet been fully magnetized? Has the magnet been partially demagnetized?)
- Rating of the coercivity HcJ of the magnetic material after exposure at different temperatures in the sheared condition
