Let us consider a system of N spin 1/2-particles per unit volume in thermal equilib- rium in a constant external magnetic field B. Such system of particles will tend to orient along the magnetic field resulting in a bulk magnetization M. (a) Give an expression for this magnetization (b) What is the magnetization in the high-temperature limit, to lowest nontrivial order?
