Receiving a metal powder in a container, and the art, using a woman (勵磁) coil arranged outside the container and applying an alternating magnetic flux (磁 束) to the metallic powder of the alternating magnetic flux passed through the said metallic powder said container detected by a detection coil disposed on the outside, by using a pre-prepared calibration curve with respect to the amplitude of the detected alternating magnetic flux, a correlation between the amplitude of the apparent density and the AC magnetic flux in the metal powder relationship, to obtain the apparent density of the metal powder, by the bulk density measurement method, the process for producing a powder mixture or, without interrupting the production process of the powder compact, on-line and makes it also possible to measure with high accuracy the apparent density of the metal by the non-contact method, powder.
