Simulation of the Gouy balance method for determining the magnetic susceptibility, (very much a rough DRAFT):
sample-1 ([Cr(urea)6]Cl3 - green) using calibrant-1 (Hg[Co(NCS)4] - blue)         sample-2 (K3[Cr(ox)3].3H2O - blue) using calibrant-3 (CuSO4.5H2O - blue)
sample-3 (Cr(acac)3 - purple) using calibrant-2 ([Ni(en)3]S2O3 - purple)

W1 W2 W3 W4 W5 W6 W7 Finished
Power supply is OFF 0 V DC

W1-weight of the empty tube - magnet OFF= W1
W2-weight of the empty tube - magnet  ON= W2
W3-weight of the tube with water- magnet OFF= W3
Calibrant used calibrant
       W4-weight of the tube and calibrant - magnet  OFF= W4
       W5-weight of the tube and calibrant - magnet ON= W5
Sample used sample
       W6-weight of the tube and sample - magnet OFF= W6
       W7-weight of the tube and sample - magnet  ON= W7
Temperature for ALL measurements was 300K

For the complex being studied, you need to provide the RMM
and the diamagnetic correction value.
RMM (Molar Mass)    RMM
diamagnetic correction    DC

Chig (χg) is 0       Magnetic moment (μ) is 0 BM

An alternative page allows you to enter your own values and calculate the magnetic moment.

The rotatable model designed by Craig Walters and Dominique Lyew in 2008 for the virtual world "Wonderland" allows for an all-around view of the Gouy Balance
