Introduction For this experiment, we used an experimental arrangement of a Gouy balance to measure the susceptibility of various samples. ... For our experiment, in order for us to obtain the susceptibility of a sample, we first calibrate the balance with a standard sample of known susceptibility, that is we find the magnetic force on a sample of known susceptibility and we compare this force to the unknown sample of same size and packing, finally the susceptibility of the unknown will be determined by using the ratios of the two forces and the appropriate equations for calculating the susc...
