AI Thread Summary
The discussion focuses on determining the appropriate susceptibility of Bismuth to calculate for an experiment. The user is uncertain whether to use molar, mass, or volume susceptibility, as the experiment did not specify. The formula provided involves susceptibility (X) and requires matching its units with the different types of susceptibilities listed. It is noted that volume susceptibility is unitless, which aligns with the experiment's findings. Ultimately, clarity on the units of susceptibility is essential for accurate calculations.

I am trying to find the susceptibility for Bismuth, but I don't know which one I am after. Wikipedia gives molar, mass and volume. In my experiment we where asked to calculate the susceptibility, but not which one so I don't know which one I should compare with.

In the experiment we used the formula

Fz = -(1/2mu0)*XA(B21-B22)

Where Fz is the force in direction z, against gravity
X is the susceptibility
A is the area
B1 is and B2 are magnetic flux at different points,

MaxManus is hoping for the best

What are the units of X that is used in your formula or textbook? If you compare that with the units of the molar-, mass-, volume-based susceptibilities, one of them should have the same units.
 
Thanks. Volume was unit less, the same was the answer in my experiment
 
Sounds good!
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
