GEOLOGY

Detailed explanation-1: -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-2: -Do all atoms have magnetic fields? The answer to this question is yes and no. All the electrons do produce a magnetic field as they spin and orbit the nucleus; however, in some atoms, two electrons spinning and orbiting in opposite directions pair up and the net magnetic moment of the atom is zero.

Detailed explanation-3: -Magnets have two poles, a north pole and a south pole. The magnetic field is represented by field lines that start at a magnet’s north pole and end at the south pole. When most people think of magnetism, they think about the magnetic force experienced between two magnets.

Detailed explanation-4: -In theory, every atom or molecule has the potential to be magnetic, since this depends on the movement of its electrons. Electrons move in two ways: Spin, which can loosely be thought as spinning around themselves, and orbit, which refers to an electron’s movement around the nucleus of its atom.
