Computational techniques in the first course on electromagnetism

摘要

It is widely acknowledged that the introductory engineering electromagnetics (EM) course is in trouble because its concepts and techniques are novel and difficult, the time allowed is insufficient, and the range of topics is great and expanding. The introduction of computer-numerical solutions and the advantages and disadvantages of various approaches are discussed. It is suggested that the use of spreadsheet capabilities is pedagogically advantageous and time-effective for solving Laplace's equation problems by the method of finite differences.
