Detailed explanation-1: -Magnetic fields are produced by moving electric charges. Everything is made up of atoms, and each atom has a nucleus made of neutrons and protons with electrons that orbit around the nucleus. Since the orbiting electrons ≠are tiny moving charges, a small magnetic field is created around each atom.

Detailed explanation-2: -“A magnetic field is the area around a magnet, magnetic object, or an electric charge in which magnetic force is exerted.” Huh? Let’s put it this way. The invisible area around a magnetic object that can pull another magnetic object toward it or push another magnetic object away from it is called a magnetic field.

Detailed explanation-3: -A magnetic field describes a volume of space where there is a change in energy. As Ampere suggested, a magnetic field is produced whenever an electrical charge is in motion. The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire.

Detailed explanation-4: -The magnetic field is a region around a magnetic material or a moving electric charge within which the force of magnetism acts. A magnetic field is a force field that is created by moving electric charges and magnetic dipoles and exerts a force on other nearby moving charges and magnetic dipoles.

Detailed explanation-5: -Magnetic fields are produced by moving electric charges and the intrinsic magnetic moments of elementary particles associated with a fundamental quantum property, their spin.
