The research aims are for studying and calculation spin – orbit energy correction and Darwin’s correction when   0
for positronium atom, in addition to that we calculate magnetic energy correction as a function of weak magnetic field
(anomalous Zeeman effect) with range (10 m Tesla -100 m Tesla ) and strong magnetic field with range (25 Tesla-50
Tesla) for electron spin upward and downward with s=±1/2 we found the magnetic energy correction of the positronium
atom increases with a magnetic field strength (B) according to the empirical formula.

Keywords: Simulation, spin, Zeeman Effect, Paschen-Back, Positronium atom.
