At present the most popular, and most commonly applied, permanent magnets are ferrite and neodymium magnets. Their broader and broader industrial use connected with the drop of the costs of their production is connected with the need to broaden the basic tests evaluating their influence upon the functions of living organisms. So far only few studies cited in the world's medical literature have been devoted to the problem of evaluating the activity of permanent magnetic fields onto cell cultures. The permanent magnets used in the studies had no descriptions of their characteristics nor previously prepared spatial models of distribution of the permanent magnetic field intensities. Our goal was an attempt to optimize these studies. We created computer simulations of 3D distribution of the intensities of the permanent magnetic field for several permanent magnets, which, as we assumed, could be used for tests with cell cultures. The next step was the construction of model circuits for several sizes of magnets on the basis of the spatial parameters of a standard plastic container used for growing cell cultures. We compared the assumptions of the intensity simulations with real measurements carried out on models of real circuits. Our research is to be developed in a proposal of a model for testing the impact of permanent magnetic fields on various factors of cell cultures in vitro. Our Assumption are based on the existing 3D simulations carried out for permanent magnets used in the production of electric engines. The calculations of the magnetic induction were carried out with the application of the 3D finite elements method. The results of the measurements were presented in a form of visualization of 3D distribution of the simulations and the real measurements. The measurement differences were statistically compared; no statistically significant differences in the computer simulations (on the basis of the producer's assumptions) and the real measurements were revealed. 3D simulations allow to select appropriate parameters of magnets and to provide design preparation of stations for testing the impact of permanent magnetic fields onto cell cultures.
