    "abstract": "It is shown that the spin is naturally introduced into classical mechanics if\nthe latter is formulated as dynamics of the phase space density. It is shown\nthat the uncertainty principle, as the amendment in this dynamics, restricts\npossible spins, and in particular equation for the particle with the spin\n$\\hbar /2$ is derived. Also equation for the charge with this spin is derived\nwhen electromagnetic field is included. In one example it is shown that the\nmodulus of the spin changes with the gradient of the magnetic field.",
