Ferromagnetic: meaning, definitions and examples
🧲
ferromagnetic
[ ˌfɛroʊˈmæɡnətɪk ]
magnetism property
Ferromagnetic materials have the ability to become magnetized and retain their magnetization even after the external magnetic field is removed. This property is due to the alignment of magnetic moments of the atoms in the material. Common ferromagnetic materials include iron, nickel, and cobalt.
Synonyms
magnetic, permanent magnet.
Examples of usage
- Iron is a well-known ferromagnetic material.
- The ferromagnetic properties of nickel make it useful in various applications.
- Ferromagnetic materials are essential in the construction of motors and transformers.
Etymology
The term 'ferromagnetic' is derived from 'ferro-', which comes from the Latin word 'ferrum', meaning iron, and 'magnetic' from the Greek word 'magnetis', colloquially referring to magnetism. The concept first emerged in the 19th century when scientists began to understand the magnetic properties of different materials. Initial studies focused on iron because of its strong magnetic properties, leading to the categorization of materials based on their magnetic behavior. Over time, the term has expanded to include other metals such as cobalt and nickel, which exhibit similar ferromagnetic characteristics. Research into ferromagnetism has significantly contributed to advancements in technology, particularly in electronics and telecommunications.
