The MPN measurement system can accommodate samples either in loose powder form, or as stacked pressed pellets or as a single solid piece (usually cut by diamond sawing or by diamond core-drilling). This allows the experimenter the option of choosing the physical state required, and, more importantly for practical applications, to do the measurements at the required density!

After measurement of µ′ and µ′′, the values of the magnetic tanδ_m can be calculated ( see formulas in “Details of Technique” menu ).
