An experiment with protons uses a magnetic field for which the energy difference between the aligned and anti-aligned spin states is 8.4×10−26J8.4×10−26J, the same as used for a medical MRI. At what temperature will the fractional population difference be ΔN/NΔ = 0.010, a 1%% difference? Temperatures this low are routinely achieved in low-temperature physics experiments.
