Simulation of Field and Inductance Spatial Distribution in Locally Magnetized Massive Objects and Optimization of U-Shaped Transducer Design

摘要

The field and magnetic-inductance spatial distributions in plates that differ in geometric dimensions and magnetic properties, which were magnetized locally by U-shaped electromagnets of different standard sizes, were calculated using the finite element method. The magnetic-flux side scattering, which impedes the magnetization, was estimated qualitatively. Recommendations on designing magnetizing instruments, which are characterized by low side scattering, are given.
