Any hint in the right direction is helpful?

Homework Statement given the following position vector: R = (10n1 + 9n2 + 19n3)(a/10) x + 6(n2+n3)(a/5) y + 2(n3)a z where n1, n2 and n3 are integers Find the primitive lattice vectors. Homework Equations any position vector of a lattice point is of the type R= c1 a1 + c2 a2 + c3 a3; and...

Yea, I got that a few minutes ago, I can't believe I was so absent minded :) Thank you for your help. :)

I know my equation is correct :p Another PF user helped me a lot to get there. I'm asking about the uncertainty of χm

http://en.wikipedia.org/wiki/Magnetic_susceptibility#Mass_susceptibility_and_molar_susceptibility

χm is the mass susceptibility and it has units of m3/kilogram m is the mass of the sample I am measuring it's susceptibility.

Homework Statement Alright so I'm writing a lab report and I am running into a problem of finding the error on this value. I am measuring the magnetic susceptibility of a couple of samples. My lab manual and instructor told me the error on the force is related to the error on the derivative of...

and the 103/4π is to convert it to cgs units? If yes I understand everything now :) Thank you so much for your help. I really appreciate it.

Im not sure I understand. So the equation become Fx = v/(2u0) * χm* dH2/dx?

The first two pictures are the derivation. The equation is in the last picture. Equation 10. χ1 is the susceptibility of the surrounding medium which is air and that can be taken as zero. So we are left with the equation that I wrote. http://www.freeimagehosting.net/vbkkf...

The teacher gave it to me in the lab manual. I even found the same equation in other previous published papers that did the same experiment.

mass susceptibility is just the volumetric susceptibility (the dimensionless quantity) divided by the density of the material. Molar susceptibility is the mass susceptibility multiplied by molar mass. So now I understood how to convert to cgs units (thanks plenty for that), but I keep getting...

It is true that susceptibility has no units but the equation that I am using gives me the mass susceptibility, which has units of length3/mass. Does what you suggest change? Also, even if you plug in the numbers, I get a value of magnitude of few 103 instead of something close to 10-6 which begs...

1. 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...
