1. The problem statement, all variables and given/known data At T=0, what is the largest density that a gas can be completly spin polarized by a magnetic induction of 10 telsas 2. Relevant equations μn= 10^-26 J/T mass= 5*10^-27 kg spin= 1/2 3. The attempt at a solution I am really not sure where to begin. The spin polarization is the degree which the spin is aligned with a given direction and at T=0, all of the particles fall into the lowest energy level. With this, in the ground state f(ε,τ)= 1/ e^(ε-μ/τ)-1 Any help?!
