Electromagnetism refers to the branch of physics that deals with the interaction between electricity and magnetism. It explains how electric currents create magnetic fields and how changing magnetic fields can induce electric currents.
congrats on reading the definition of Electromagnetism. now let's actually learn it.
Magnetic Field: A magnetic field is an invisible region around a magnet or current-carrying wire where magnetic forces are exerted on nearby objects.
Induction: Induction refers to generating an electric current in a conductor by exposing it to a changing magnetic field.
Electromagnetic Wave: An electromagnetic wave consists of oscillating electric and magnetic fields that propagate through space, such as radio waves, microwaves, visible light, and X-rays.
