REFORMED MAGNETIC FLUID, AND GRIPPING MECHANISM AND GRIPPING DEVICE WHICH USE REFORMED MAGNETIC FLUID

摘要

The present invention provides a reformed magnetic fluid (11) which achieves improved holding strength during magnetization by mixing, into a magnetic fluid (27) having a base liquid and ferromagnetic fine particles (25) present in a dispersed state in the base liquid, nonmagnetic powder (26) having a larger size than that of the ferromagnetic fine particle (25) and a smaller specific gravity than that of the ferromagnetic fine particle (25), and a gripping mechanism (10) and a gripping device (30) which use the reformed magnetic fluid (11).
