What is electromagnetism?

Electromagnetism is a branch of physics that studies the relationship between electric fields and magnetic fields. It describes how electric charges and currents interact with magnetic fields and vice versa. The fundamental equations of electromagnetism are Maxwell's equations, which form the basis for understanding the behavior of electric and magnetic fields in various situations. Applications of electromagnetism range from everyday technologies like electric motors and generators to more advanced concepts like electromagnetic waves, which include radio waves, microwaves, and light.
