Homework Help: Magnetisation ratio in human body using gyromagnetic ratios

  1. Oct 31, 2016 #1
    1. The problem statement, all variables and given/known data
    The number density of 1H nuclei in the body is roughly 600 times greater than that of 13C
    nuclei. By what factor is the magnetisation M0 of 1H greater than 13C in the same external magnetic
    2. Relevant equations
    3. The attempt at a solution

    Surely it can't be as simple as dividing the gyromagnetic ratio of 1H by 13C? I've thoroughly went through my notes and have been unable to find any appropriate equation to solve this.

    How does M0 scale with the Larmor frequency? How does M0 scale with number density? Are there any other relevant scaling factors?
