Abstract

A method for controlling the homogeneity of magnetization of magnets is proposed, based on the experimental determination of the magnetic field strength on the polar surface of a magnet of various shapes. If the experimental value of the magnetic field deviates from the calculated value determined by the characteristics specified in the corresponding GOST, the magnets are rejected by more than 10 %. To perform calculations of the magnetosilic properties of mechanisms, it is proposed to use an experimentally determined average value of magnetization. Theoretical formulas for determining the magnetic field of prismatic, cylindrical and annular magnets are obtained using the equivalent solenoid method.
