GEOLOGY

Detailed explanation-1: -Magnetic materials are those which are attracted to a magnet. Examples of such materials include iron, nickel, and cobalt, etc. whereas materials like plastic and wood are non-magnetic.

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. This, in turn, creates an attraction between the two magnetized objects.

Detailed explanation-3: -The metals that are magnetic (attracted to magnets) are also the metals that can be made into magnets. The most common magnetic metal is iron which is the main substance in steel. Iron is also in a mineral called loadstone which is the most magnetic naturally-occurring mineral.

Detailed explanation-4: -Iron is an extremely well-known ferromagnetic metal. It is, in fact, the strongest ferromagnetic metal. It forms an integral part of the earth’s core and imparts its magnetic properties to our planet. That is why the Earth acts as a permanent magnet on its own.

Detailed explanation-5: -Magnets are made of a group of metals called ferromagnetic metals. Nickel and iron are examples of these metals. Metals such as these are unique in their ability to be magnetized uniformly.
