In the article, an electromagnetic circuit assigned to magnetize permanent magnets was presented. Design issues and possibilities of magnetizer were discussed and two computational models were shown. A schedule of the magnetic field strength was expressed in the air gap of magnetizer. An influence of the leakage inductance, magnetizing coil on magnetic field strength value, inside the permanent magnet was discussed. Computational temporary courses of voltage and current in the magnetizing coil, during the process of magnetizing were presented. Results of calculations and simulations were displayed. Possibilities of the presented electromagnetic circuit were discussed in the perspective of getting greater values of magnetic field strengths, inside the permanent magnet, during the magnetizing process.
