GEOLOGY

Detailed explanation-1: -When you place the north pole of one magnet near the south pole of another magnet, they are attracted to one another. When you place like poles of two magnets near each other (north to north or south to south), they will repel each other.

Detailed explanation-2: -Magnets attract iron due to the influence of their magnetic field upon the iron. When exposed to the magnetic field, the atoms begin to align their electrons with the flow of the magnetic field, which makes the iron magnetized as well.

Detailed explanation-3: -All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other.

Detailed explanation-4: -Metals that naturally attract magnets are known as ferromagnetic metals; these magnets will firmly stick to these metals. For example, iron, cobalt, steel, nickel, manganese, gadolinium, and lodestone are all ferromagnetic metals.
