What are the dimenstions of chi , the magnetic susceptibility? Consider an H-atoms. Guess an expression for chi , upto a constant by constructing a quantity of dimenstions of chi , out of parameters of the atom: e, m, v, R and mu_0 . Here, m is the electronic mass, v is the electronic velocity, R is Bohr radius. Estimate the number so obtained and compare with the value of |chi| ~ 10^-5 for many solid materials.
