The resulting model is a system of three equations each of which is responsible for a separate proceeding process. The developed model is relevant for the assessment of electromagnetic drivers, using the method of natural-model tests. The method of natural-model tests combines measurement known quantities on the physical object and measure the required variables in the model.
