In this work we propose an electromagnetic model of the neutron inspired by the theoretical foundations outlined by Vassallo and Celani, according to which elementary particles can be interpreted as small spheres, massless, charged, in motion. The model assumes that the neutron is made up of two opposite charges, without rest mass, in circular motion on concentric orbits. Each generates a current and therefore a magnetic moment. The approach allows to calculate, starting from simple classical and quantum relations, the values u200bu200bof the magnetic moment, the mass and the spin of the neutron, obtaining results consistent with the experimental data. Finally, the analysis of the dynamic stability of the system is addressed, considering the internal electromagnetic forces and the relativistic evolution along the z-axis. The model, although phenomenological, opens to original reflections on the structure of matter and on the role of the electromagnetic field in the origin of mass.
