When a particle with spin 1/2 is placed in a magnetic field H , its energy level is split into -mH and +mH and it has a magnetic moment m or -m along the direction of the magnetic field , respectively. Suppose a system consisting of N such particles in a magnetic field H and is kept at temperature T. Find the internal energy , the entropy, the specific heat and the total magnetic moment M of this system with the help of canonical distribution.
