. Good day,
Using 4-inch pole caps and a Mettler M5 balance, I got all the values required in order to calculate the magnetic susceptibility of several inorganic compounds such as Manganese (IV) oxide (MnO2). I have the change in mass of the tube with the sample of the compound when the magnetic field is on and when it is off. I got the mass of the sample as well as the region where the gradient of the magnetic field (dH^2/dx) (x being the vertical direction) is constant.
I know my values to be right but I am having a lot of trouble converting to cgs units.

2. Fx= m/2 * µ0 * ?m * dH^2/dx
where ?m is the mass susceptibility of the sample.

3. Lets take MnO2 as an example,
Fx = ?m*g = 0.0517 grams * 9.81
dH^2/dx = 6.29169 (This is the value of the slope of B^2 in Tesla squared and x in meteres
m= 1.1765 grams

This gives mass/specific susceptibility which is incredibly larger than the literature value (on the order of 10^6)
The literature value of the MOLAR susceptibility is 2280x 10^-6 in cgs units
