We carried out the Stokes diagnostic of new two-dimensional magnetohydrodynamical models (MHDM) with continuum evolution of the magnetogranulation in course of 2 hours of hydrodynamical (solar) time. The results show a satisfactory agreement with the results of Stokes diagnostics of solar-small magnetic flux tubes observed in quiet network elements and active plages. The straightforward methods which are often used in Stokes diagnostics of solar magnetic elements were tested by means by means of MHDM. The most reliable methods are determination of magnetic field strength from the separation of the peaks of Stokes V profiles of the Fe I λ 1564.8 nm infrared line and determination of the magnetic inclination angle from the ratio of tg2γ ≈ {(Q2+U2)}1/2/V2. The lower limits of such determinations are about 20 mT and 10° respectively.
