Electromagnetism
Electromagnetism is a branch of physics that involves how electrically charged particles interact. It describes how electricity and magnetism operate together to produce phenomena like light and electromagnetic waves. When electric current flows, it creates a magnetic field, and a changing magnetic field can generate an electric current. This interplay is central to many modern technologies, such as lighting, telecommunication, and electrical power.

Electromagnetism is a fundamental force of nature that describes the interaction between electric charges and magnetic fields. It is responsible for electricity, magnetism, and light. When electric charges move, they create magnetic fields, and changing magnetic fields can induce electric currents. These principles underlie many technologies, such as electric motors, generators, and wireless communication. The unification of electricity and magnetism into a single framework was a significant achievement in physics, leading to Maxwell's equations, which describe how electric and magnetic fields interact and propagate through space.
