Determining Cavity Shape and Size in Homogeneously Magnetized Magnets within the Framework of a Two-Dimensional Model
摘要
Abstract
For extended uniformly magnetized bodies, a practical implementation of a numerical algorithm for solving an integro- differential equation on a function that defines the localization, shape, and size of a cavity in such a magnet based on the measured resulting field outside of it has been investigated. A program in the FORTRAN language that implements the above algorithm has been compiled. The shape, dimensions, and position of a noncoaxial cylindrical cavity in the magnet were reconstructed as a test and illustrative example of the studied algorithm for a uniformly magnetized cylindrical magnet.
