Toroidal models for the electron are given by several authors. Essential ingredients in these models are: a radius r₁ of the torus, a radius r₂ of the tube of the torus and a toroidal factor N, defined as the angular frequency of the charge rotating around the centre of the tube divided by the angular frequency of the charge rotating around the centre of the torus. The proposed model is extended to the muon and the tau lepton, as well as to the three observed neutrinos. Furthermore, the total energy of all leptons is split into two parts: the first part depends on radius r₁ and the second part on radius r₂.

Agreement between predicted and observed magnetic dipole moments, first order anomalous correction included, is obtained for all charged leptons. In addition, for all these leptons the same ratio between the radii r₁ andr₂, depending on the fine-structure constant, is found. Moreover, the same value N = 1 is compatible with the observed magnetic dipole moment of all charged leptons.

Using recently proposed theoretical neutrino masses m_i (i = 1, 2, 3) and magnetic dipole moments μ(i), the toroidal model can also be applied to neutrinos. For neutrino 1 a value of N = 1 is obtained, whereas values of N = 5.7 and N = 33 are found for neutrinos 2 and 3, respectively. Finally, the toroidal moments of all leptons are calculated. The magnitude of the toroidal moment of the neutrinos increases with increasing values of N.
