The Dirac monopole is discussed in view of the gauge invariance in Quantum Electrodynamics. It is shown the monopole existence implies the violation of the gauge invariance principle. The monopole field is essentially a longitudinal field and so a mass is naturally associated to it. Interpretation for the case the monopole charge is different from zero is addressed at the conclusion.
It is discussed the singular string associated to the gauge field of monopoles must be a physical observable if the monopole charge is different from zero. It is naturally found that if the gauge is to be an observable, it is possibly connected to gravity.
The classical electron is presented as made up of an electric charge and two Dirac monopoles of opposite charge performing a magnetic dipole. It is discussed that a valid variational principle for this system can be defined. The Dirac quantization condition for charges can be derived in Quantum Electrodynamics as monopoles are properly defined in the structure. Further comments on the subject are addressed since the proper care of Dirac strings is still an open issue.
