Gouys Balance Method
Product Code : EDS-LE-12157 Gouys Balance Method
Description
Apparatus for Measurement of Susceptibility of Paramagnetic Solids by Gouy’s Method:
In the Gouy’s method of susceptibility measurement, the solid sample in the form of a long cylinder (area of cross section A) is hung from the pan of a balance and is placed such that one end of the sample is between the pole-pieces of the magnet (field H) and the other one is out side the field.
The force exerted on the sample by the inhomogeneous magnetic field is obtained by measuring the apparent change (m) in the mass of the sample.
The susceptibility x given by:
x=2△mg/AH²
If the sample is in the form of powder, it is filled in a long nonmagnetic tube which is then suspended from the pan of the balance.
The setup consists of the following:
(A) Digital Balance:
