GEOLOGY

Detailed explanation-1: -Magnets do not attract all metallic objects. They can only attract magnetic materials like iron, cobalt and nickel.

Detailed explanation-2: -Only ferromagnetic materials such as iron, cobalt, and nickel are attracted to magnetic fields strongly enough to be truly considered magnetic. However, all metals can be placed into one of three categories: Ferromagnetic. Paramagnetic.

Detailed explanation-3: -The metals iron, cobalt and nickel are magnetic in normal conditions, as are the alloys that are made from them, such as steel. All other metals and all non-metals are not magnetic.

Detailed explanation-4: -Magnetic forces are non contact forces; they pull or push on objects without touching them. Magnets are only attracted to a few ‘magnetic’ metals and not all matter. Magnets are attracted to and repel other magnets.

Detailed explanation-5: -Every magnet has both a north and a south pole. 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.
