Which metallic element is called ‘ferromagnetic’ because of its strong attraction?

Correct option is D

The correct answer is (d) Iron.
· Iron is classified as a ferromagnetic material due to its strong magnetic properties. This means it can be magnetized easily and maintains its magnetic properties even after the external magnetic field is removed.
· The ferromagnetic properties of iron arise from the alignment of its magnetic moments, which occur in regions called magnetic domains.
Additional Information: · Ferromagnetism: This is a property exhibited by certain materials where they can become permanent magnets. Besides iron, other ferromagnetic materials include cobalt and nickel.
· Applications: Iron's ferromagnetic properties make it essential in the production of magnets, transformers, and electrical motors. It's also widely used in various alloys, such as steel, which retains some magnetic properties.
Due to its ferromagnetic properties, iron is widely used in various applications:
· Electrical Transformers: Iron cores are essential in transformers to improve efficiency and performance.
· Magnetic Storage Media: Used in hard drives and magnetic tapes, where data is stored magnetically.
· Electromagnets: Iron is commonly used in the production of electromagnets, which are essential in electric motors, generators, and various industrial applications.
· Permanent Magnets: Alnico (an alloy of aluminium, nickel, and cobalt) and ferrite magnets often contain iron, enhancing their magnetic properties.
