Hi, Anthony. I hope you are having a good day. I would just like to thank you so much for the help that you have given me in answering and providing crucial information for my experiment. I cant thank you enought for what you have done. Once again, and honestly, thank you so much!  Fineas When I did the initial calculations for B^2/z=mu_0*p*G/x I found that the answer of mu_0*p*G/x was negative, but any answer of B^2/z will be positive. How do I solve this problem, the formula doesnt seem to work out?

Answer 1:
I'm glad I've been helpful!! Your answer for mu_0*p*g/x shouldn't be negative. I think I may have not defined g correctly for you before, so let's take a look at what the values should be: mu_0 = 1.2566*10^{6} T*m/A p = 9780 kg/m^{3} (This is only true for Bismuth) g =  9.81 kg*m/s^{2} (For the equation I found, g is negative here because gravity acts downwards. Normally g is considered positive, and the negative sign comes in elsewhere, but the important thing is that it's negative here. I think this is where I made the mistake before.)x =  1.66 * 10^{4}I'm guessing you correctly used x as negative in your calculation, but missed out on g being negative since I defined it wrong. Sorry about that! It was good to notice that, though  it's always a good idea to take a look at your answer and think about whether it makes sense or not.
