Electromagnetism is a branch of physics that deals with the study of the relationship between electric fields and magnetic fields. It was first formulated as a unified theory by James Clerk Maxwell in the 19th century through Maxwell's equations. These equations describe how electric charges and currents generate electric and magnetic fields, and how changes in these fields can induce each other. Electromagnetism plays a fundamental role in our understanding of the behavior of charged particles, electromagnetic waves (such as light), and the operation of devices like electric motors, generators, and transformers. It is one of the four fundamental forces of nature and is essential for the functioning of many modern technologies, including telecommunications, electronics, and power generation.
Electromagnetism section of electronics-tutorials.ws, you will learn the fundamental principles of electromagnetism. This includes understanding concepts like electromagnetic fields, magnetic induction, and the relationship between electric currents and magnetic fields. You'll delve into Faraday's and Lenz's laws, which describe electromagnetic induction, and explore how electromagnetic waves propagate through space. The tutorials also cover practical applications of electromagnetism, such as electromagnetic coils, transformers, and electromagnetic interference (EMI) mitigation techniques. This knowledge forms the basis for understanding and designing electrical and electronic systems that rely on electromagnetic phenomena.
