The gyromagnetic ratio  of a particle or system is the ratio of its magnetic moment to its angular momentum. Its value is $ 8.8\times 10^{10}C/Kg$

Permeability of free space is $ \mu_0 = 12.56\times 10^{-7}T-m A^{-1}$

Earth’s magnetic field at equator is $ B = 4\times 10^{-5} T$

Bohr magnetron is $ \mu_B = \frac{eh}{4\pi m} = 9.27\times 10^{-24} A-m^2$
