DEVICE FOR MEASURING THE MAGNETIC SUSCEPTIBILITY OF LIQUIDS OF VARIABLE COMPOSITION
Annotation
A scheme of instrument for measuring the relative magnetic susceptibility of weak-magnetic liquids is proposed. The operation principle of the measuring device is based on the effect of change in magnetic field induction inside a cavity of hard-magnet ball when it is enveloped by the spherical layer of the substance under measurement. The measurement of susceptibility may be executed not only with a nonmoving object but in flowing liquid, too. Resolution of the instrument is predicted to be 10–9 in CGS system of units. The resolution enables evaluation of the ethanol concentration in water with the accuracy of about one volume percent.
