GEOLOGY

Detailed explanation-1: -Steel is an iron-based alloy. Most forms of steel, including stainless steel, are magnetic.

Detailed explanation-2: -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-3: -Iron, Nickel, and Cobalt are the magnetic substances as objects made up of these materials are attracted by a magnet. Also, magnetic materials can be magnetized or we can say that magnetic materials can be converted into magnets.

Detailed explanation-4: -Examples of magnetic substances include iron, nickel, cobalt, stainless steel, and many rare earth metals. Diamagnetic materials like copper and gold are weakly repelled by a magnetic field. Paramagnetic materials like calcium and aluminum are weakly attracted by a magnetic field.

Detailed explanation-5: -Iron. Nickel. Cobalt. Some alloys of rare earth metals. 27-Oct-2015
