Visualization of Electric Multipole Moment and Magnetic Multipole Moment With MATLAB
Abstract: In Electromagnetism, there are many methods to deal with electromagnetic field problems, where, electric multipole moment method and magnetic multipole moment method are two simple and applied methods of solving problems in electrostatic field. This thesis aims to make the image of electric field magnetic field of electric multipole moment method and magnetic multipole moment method visible, and to make the abstract electromagnetic field shows its physical shape more vividly, with the mathematical proof of electric multipole method and magnetic multipole moment method, with the calculation of simple charged system of electric dipole moment, electric quadrupole moments,electric octupole moment and the magnetic dipole moment, and most importantly, with the help MATLAB. This thesis can also give readers a vivid picture about electromagnetic field in their brains, so that they can better understand and grasp the knowledge of the lectromagnetic field theory. 源`自*六)维[论*文'网www.lwfree.cn

电磁学是整个物理系统理论中不可缺少的部分，整个完整的电磁场理论的建立将物理学推进一个新领域，也促进了世界的发展，是物理学史上的又一个的里程碑。在学习电磁学理论不仅要有普通物理学的知识作为基础，而且还要掌握一定的高等数学知识作为处理和分析物理公式的工具，不然仅仅只是依靠普通物理知识是不能够完全理解和掌握电磁学其中的奥秘，也无法感受到电磁场的美丽图形。抽象的电磁学基础理论知识和繁琐的数学计算，使得学习电磁学变得更加困难，本文针对电多极矩法和磁多极矩法求解的抽象的电磁场问题通过用MATLAB软件将其形象的转换为直观的物理图形，也即是运用形象思维在去理解抽象的物理问题。 电多极矩与磁多极矩的MATLAB可视化+代码:http://www.lwfree.cn/wuli/20181230/28416.html
