Quinck's Tube Method
Item Code : SK069
Principle and Working:
Quinck’s method is based on the force experienced by a magnetised material in a non-uniform magnetic field and is a version of Gouy’s method. It is specially adapted for liquids.
In this setup, a liquid in a U-tube rises under the force of the magnetic field until the magnetic force balances the pressure difference caused by a height change h, between the two arms.
The relationship is:
A (X-Xa).(B2-B02)=2 µ0h (ρ-ρa)g
Where: X : Susceptibility of the liquid, Xa : Susceptibility of air, B1 −B0 : Magnetic field strengths, μ : Permeability of free space, ρ-ρa : Densities of the liquid and air, g: Acceleration due to gravity, By plotting h versus B2, the susceptibility X is determined from the slope.
