Electromagnetics is a branch of physics that studies the interactions between electric charges and magnetic fields. It explores how electric and magnetic fields are generated by charged particles, how they affect those particles, and their interactions with each other. Key principles within this field include Coulomb’s law for electric forces, Ampère’s law and Faraday’s law for magnetic phenomena, and the induction of electromotive forces. Electromagnetics is fundamental to understanding and designing a wide range of applications, from electrical and communication systems to various types of motors and generators. Maxwell’s equations, formulated by James Clerk Maxwell in the 19th century, elegantly describe the fundamental laws of electromagnetism and have profoundly impacted modern technology and theoretical physics.
