GEOLOGY

Detailed explanation-1: -Magnetic fields occur whenever charge is in motion. As more charge is put in more motion, the strength of a magnetic field increases. Magnetism and magnetic fields are one aspect of the electromagnetic force, one of the four fundamental forces of nature.

Detailed explanation-2: -All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

Detailed explanation-3: -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-4: -When a conductor is placed in a magnetic field and current flows in the conductor, the magnetic field and the current interact each other to produce force. The force is called “Electromagnetic force".

Detailed explanation-5: -“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.
