Simulation and Analysis of Static Magnetic Fields Based on COMSOL Multiphysics

本文采用COMSOL软件模拟了一个半径为5毫米的圆柱形微型永磁体的磁场分布，并通过切片视图和体积箭头图示，对磁铁周边的磁场进行了全方位的三维可视化分析。同时，利用一维绘图集合深入探讨了磁铁边缘平行路径上各点的磁场特性。该仿真方法使得我们能够精确计算出磁铁周围特定路径或任意点的磁场强度，不仅提升了磁场理解的直观性和形象性，也为大学物理实验的教学提供了有力的辅助工具。
This paper employs COMSOL software to simulate the magnetic field distribution of a cylindrical micro-permanent magnet with a radius of 5 millimeters. Through the use of slice views and volume arrow diagrams, a comprehensive three-dimensional visualization analysis of the magnetic field surrounding the magnet is conducted. Additionally, a one-dimensional plotting set is utilized to delve into the magnetic field characteristics of points along parallel paths at the edge of the magnet. This simulation method enables us to accurately calculate the magnetic field intensity at specific paths or arbitrary points surrounding the magnet, not only enhancing the intuition and imagery of magnetic field understanding but also providing a powerful auxiliary tool for teaching in university physics experiments.
