Porosity measuring device and porosity measuring method

Abstract

A porosity measuring device (10) according to the present invention includes a magnetic field generating section (20), a dispersoid measuring section (30) configured to measure movement of a dispersoid (s) dispersed in a dispersion medium (m) in a state where a magnetic field is generated by the magnetic field generating section (20), and an operating section (40) configured to obtain a porosity of the dispersoid (s) on the basis of a measurement result of the dispersoid measuring section (30). The operating section (40) obtains a magnetophoretic velocity of the dispersoid (s) from the measurement result of the dispersoid measuring section (30). The operating section (40) preferably obtains the magnetophoretic velocity of the dispersoid (s) from the measurement result of the dispersoid measuring section (30).
