What is electromagnetism? #physics#iit

*Electromagnetism Explained:*

Electromagnetism is a branch of physics that deals with the study of the electromagnetic force, a fundamental interaction between electrically charged particles. It encompasses both electricity and magnetism and describes how electric charges and currents interact with magnetic fields.

1. **Electricity**: Electromagnetism explains the behavior of electric charges and electric fields. It describes how charges create electric fields around them and how these fields exert forces on other charges.

2. **Magnetism**: Electromagnetism also explains the behavior of magnets and magnetic fields. It describes how moving charges (electric currents) create magnetic fields and how these fields interact with other magnetic materials and currents.

Key concepts in electromagnetism include Maxwell's equations, which describe the behavior of electric and magnetic fields, as well as phenomena like electromagnetic induction and electromagnetic waves (including light).
