Polzunov Altai State Technical University, 46 Lenina avenue, Barnaul, Altai region, 656038, Russian Federation Abstract The authors describe the method of calculating the magnetic induction in the working gap when the magnetic-abrasive machining of flat surfaces of workpieces made of ferromagnetic materials and non-magnetic inductor with permanent magnets. The magnetic system is designed in Ansys environment, which will be carried out and the calculations presented. The picture shows the field lines for magnetic-abrasive machining of ferromagnetic and non-magnetic blanks. Also the values of magnetic induction in the working gap and in the whole magnetic system as a whole when the magnetic-abrasive machining of ferromagnetic and non-magnetic blanks. In the end, calculations showed the distribution of magnetic-abrasive powder in the working gap, depending on the material of the workpiece. For magnetic-abrasive machining of the workpiece of ferromagnetic powder in the working gap is concentrated under the poles of the inductor. For magnetic-abrasive machining of the workpiece is non-magnetic powder concentrated under the magnets, and not under the poles of the inductor.
