The input equations describing the electromagnetic field interaction with the substance are suggested.  By means of the methods of the similarity and dimensional theory,  the system of equations of magnetomechanothermodiffusion and mechanics is reduced to a dimensionless form. Quantitative analysis of dimensionless criteria for the case of hydrogen diffusion in ferrum is carried out for three different meanings of initial temperature.  The phenomena, for which dimensionless parameters are much less than a unit are not considered.  A reduced coupled system of equations of the model for determination the concentration and temperature is written.
