Electromagnetism is a branch of physics that deals with the interactions between electric charges and magnetic fields. It encompasses several fundamental principles, including Coulomb’s law, which describes the electrostatic force between charged particles; Ampère’s law, which relates magnetic fields to electric currents; and Faraday’s law of electromagnetic induction, which describes how a changing magnetic field induces an electromotive force (EMF) in a conductor. Electromagnetism has numerous applications in technology, including electric motors, generators, transformers, electromagnetic waves (such as radio waves, microwaves, and light), and various electronic devices (such as computers, smartphones, and magnetic resonance imaging machines). Understanding electromagnetism is crucial for the development of modern technology and its applications in various fields.
