Abstract :The validity of Ehrenfest`s theorem with its classical correspondence has been justified for the manifestly covariant equations of dyons. We have also developed accordingly the Lagrangian formulation for electromagnetic fields in a minimum coupled source giving rise to conserved current of dyons. Applying the Gupta subsidiary condition we have extended the validity of the Ehrenfest`s theorem for $U\leftinsert ignore into journalissuearticles values(1\right);\times U\leftinsert ignore into journalissuearticles values(1\right);$ Abelian gauge theory of dyons. It is shown that the expectation value of the quantum equation of motion reproduces the classical equation of motion, which is the generalized form of Ehrenfest`s theorem in quantum field theory.
