The nature of spin current and the separation of charge current and spincurrent are two of the fundamental questions in spintronics. For this purposethe classical limit of the Maxwell-Dirac theory is investigated in the presentcontribution. Since the Dirac equation reduces to the Weyl equation formassless particles, a vortex solution is obtained for the Weyl equation and itis argued that mass has stochastic origin. The Weyl vortex is embedded in aGaussian wavepacket to define physical vortex. Two-vortex internal structure ofelectron is developed in terms of Weyl and sub-quantum Weyl vorticescharacterized by $\hbar$ and $f=e^2/2\pi c$ respectively. It is suggested thatthis model may find application in spintronics with a new perspective.
