Abstract
I consider the effects on the energy of free electrons produced by an applied magnetic field starting with the simplest case of a one electron state with a certain helicity. The general expression of the effects is fixed by the value of the helicity and by the values of the components of the associated magnetic potential. In the realistic case of a constant magnetic field, I show with a simple example that the energy shift can be expressed in terms of the components of the field in the space directions and strongly depends on the field orientation, which could enhance the effect or decrease it in a drastic way. The possibility of an extension of this result to a realistic organic system is considered as a future goal.
