Theoretical concepts in electromagnetism

Electromagnetism is a fundamental branch of physics that studies the interaction between electric charges and magnetic fields. It explains how electric currents create magnetic fields (like in wires), while moving magnets can generate electric currents (as in generators). This dual relationship is encapsulated in Maxwell's equations, which describe how electric and magnetic fields propagate through space and can influence each other. Electromagnetism is responsible for everyday phenomena, like how electric devices work, and underpins technologies including radio waves, light, and wireless communication, making it essential to modern life.
