A novel spreadsheet based two dimensional electromagnetic solver

It is important to understand magnetic fields and their interactions in electrical equipments, transmission cables etc. But very often, visualizing magnetic fields is a difficult task. For this purpose, engineers make use of various Finite Element Analysis (FEA) softwares. In many cases, these commercial softwares are expensive and cumbersome to use. This paper illustrates a method to compute and visualize magnetic fields in two dimensions using a MS Excel Spreadsheet. The finite difference method is used to solve Maxwell's equations. The results of computation are shown and the same is compared with commercial FEA software.
