The ground state wave functions are written as a four components spinor and the operators for‘ the orbital current and spin densities as a 4 >< 4 matrices. Analytical expressions for the expectation values of these opera- tors are presented by making use of hydrogenic wave function. The resulttent expressions of the current densities are substituted in the components of the magnetic field which gives unexpected results.enMagnetismMathematical physicsThesis
