AbstractThe article presents the spectral analysis method of the magnetic fields to be able to evaluate transversal and longitudinal effects, based on Fourier integral transformations. It has been determined that the expressions of the relative spectral characteristics of the braking force and power coincide. In accordance with the derived expressions, the software program Mathcad 2001 Professional was used for the calculation of the dependencies of the transversal effect on the relative spatial frequency and under different Reynolds’s numbers. The results of the calculation indicate that when increasing the width of the secondary element, the influence of the transversal effect on the braking characteristics tend to be reduced.
