INFLUENCE OF PERMANENT MAGNET SIZE ON MAGNETIC PARAMETERS BASED ON MAGNETIC SYSTEM’S APPLICATION

The workpresents the operating points of a cylindrical permanent magnet and the magnetic field parameters outside the magnetic pole depending on the application of the magnetic system (open, partially closed, and closed) at a constant volume. For the study, a cylindrical permanent magnet N35 with dimensions of 30x10[mmxmm] (base) was studied by changing the diameter and length while maintaining a constant volume. The effect of the PM dimensions on the main magnetic parameters was studied depending on the application options. The calculation results for open and closed magnetic systems, as well as the values of the magnetic field induction outside the magnet, are presented. The corresponding analyses and conclusions are made which can be useful for manufacturers and users of permanent magnets.
