METHOD OF DEMONSTRATING PHYSICAL PROPERTIES OF MAGNETIC LIQUIDS Russian patent published in 2011 - IPC G09B23/18

Abstract RU 2423738 C1

FIELD: physics.

SUBSTANCE: magnetic liquid is poured into a vessel with a flat bottom and then placed in a magnetic field. The magnetic field strength vector is aligned such that its vertical component is present. The magnetic field strength value is changed. The surface of the magnetic liquid is illuminated with light sources of different colour. Power of said sources is controlled and synchronised with the magnetic field strength value.

EFFECT: easy use and clear demonstration of physical properties of magnetic liquids.
