Gouy’s Method

Code:
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 outside 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 is given by

= 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 set up consists of the following:
a) Digital Balance, LSCA-44
Capacity 40 gms
Readability 0.0001 gms
Repeatability ± 0.1 mg
Linearity ± 0.2 mg
Pan Size ± 80mm
Standard Bidirectional RS-232 interface
Special Feature Weight below hook for GMX-02
 
b) Sample in the form of a long rod
Aluminium sample and Glass Tube
 
c) Electromagnet, Model LSEMU-75T
Pole Peice 75mm tappered to 25mm
Mag. Field 20KG at 6mm airgap
Energising Coils Two of approx. 13Weach
Power 0-90Vdc, 3A, for coils in series
0-45Vdc, 6A, for coils in parallel
 
d)  Constant Current Power Supply, Model : LSDPS-175
e) Digital Gaussmeter, Model : LSDGM-202
 
Ordering Details:
Model LSGMX-02
