Definition
An electromagnetic field is a physical field produced by moving electric charges or changing magnetic fields. It consists of both an electric field and a magnetic field that are perpendicular to each other and propagate through space.
Magnetic flux measures how much magnetic field passes through a given area. It helps us understand how magnets interact with closed surfaces.
Electromagnetic Radiation: Electromagnetic radiation refers to the energy carried by electromagnetic waves, including visible light, radio waves, microwaves, X-rays, and gamma rays.
