especially when an occasional, single, measurement is demanded. This is a simple procedure to measure the Magnetic Moment (m) on one magnet, or one magnet array, by using one high sensitivity magnetometer. The error of the obtained Moment (m) may be easily below ±5 %. The measurement does not depend on the shape or homogeneity of the magnet under test.

measure the magnetic moment of large samples (a few cm3) in a non-destructive way17. In order to ensure that the electromagnetic force across the sensing coils is sensitive to the magnetic moment, however, these sensing coils should be dimensioned carefully and, in general, should be much larger than (at least twice) the sample size17,18, which
Equations,, give the physical observable, that component of the magnetic moment measured along an axis, relative to or along the applied field direction. Assuming a Cartesian coordinate system,conventionally, the z -axis is chosen but the observable values of the component of spin angular momentum along all three axes are each ± ħ ⁄ 2 .

Magnetic Moment easy measurement Normally, Helmholtz coils connected to an integrator are used for this measurement on one magnet, taking also into account the magnet geometry. Besides this, standardised magnets are often needed to calibrate the system. Due to all this, it results in a quite cumbersome procedure,
Measurement of magnetic moment is a convenient way to test permanent magnet materials. Other values such as operating flux density (B d), operating field strength (H d), coercive force (H c), residual flux density (B r), and maxi-mum energy product (BH max) can be derived from the meas-
