A changing magnetic field can be a source of radiated electromagnetic waves. Magnetic fields are created by the movement of electric charges. Everything is made up of atoms, and each atom has a nucleus made up of neutrons and protons, and electrons revolving around the nucleus. Because an orbiting electron is ≠ a small mobile charge, a small magnetic field is created around each atom.
An energized wire experiences a magnetic force when placed within a magnetic field produced by an external source such as a permanent magnet. Wires carrying current also generate their own magnetic fields.
