Moving electrons also creates a magnetic field, and the newly created magnetic field will oppose the original one. This holds true even for electrons on an atom.

WebbAn independent‐electron molecular‐orbital theory is developed for the diamagnetic behavior of electrons in the presence of an applied magnetic field. The molecular orbitals are written as linear combinations of gauge‐invariant atomic orbitals, the dependence of the (complex) coefficients on the magnetic field being studied by perturbation theory.
