This document serves as an introduction to the finite element method in electromagnetics and provides accompanying source code. The source code includes 4 to 5 FEM examples in 1-D and 2-D, making it suitable for beginners who want to learn the method. The finite element method is a powerful tool used in the analysis of electromagnetic fields and the design of electromagnetic devices. It involves dividing a complex geometry into simpler, finite elements and solving for the electromagnetic field within each element. By doing so, the method enables engineers to accurately predict the behavior of electromagnetic fields and optimize their designs. The examples provided in the accompanying source code will give beginners a solid foundation in the finite element method, and prepare them to tackle more advanced topics in electromagnetics and engineering.
