ferromagnet
C2Academic/Technical
Definition
Meaning
A material that possesses strong, permanent magnetic properties.
Any substance, typically containing iron, nickel, cobalt, or certain rare-earth elements, that can be permanently magnetized or is strongly attracted to a magnetic field.
Linguistics
Semantic Notes
A ferromagnet refers to the material itself, not the magnetic field it produces. It is a hyponym of 'magnet', specifying the specific type based on its underlying atomic properties.

Examples
By Part of Speech
verb
British English

Examples
By CEFR Level
- A fridge magnet is a type of ferromagnet.
- Iron is a common example of a ferromagnet.
- The strength of a ferromagnet depends on the alignment of its magnetic domains.
- Below its Curie temperature, the material behaves as a ferromagnet, exhibiting spontaneous magnetization.
Learning
Memory Aids
Mnemonic
Think 'FERRO' (like iron, Ferrum) + 'MAGNET'. It's a magnet made from 'ferrous' (iron-like) materials.
Conceptual Metaphor
A STOREHOUSE OF ALIGNED FORCE. Domains within the material are like regiments of soldiers all pointing in the same direction.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'ферромагнит' as default in casual English; use 'magnet' unless technical precision is required.
- Do not confuse with 'ferromagnetic' (adjective).
Common Mistakes
- Using 'ferromagnet' to describe a temporary magnet or an electromagnet.
- Incorrect stress: placing primary stress on the first syllable (FER-ro-mag-net) instead of the third (fer-ro-MAG-net).

FAQ
Frequently Asked Questions
Yes and no. All ferromagnets are magnets, but not all magnets are ferromagnets. Ferromagnet specifies the material's internal magnetic properties (like iron), while 'magnet' can refer to any object producing a magnetic field, including electromagnets.
Yes, if heated above a specific temperature (the Curie point), a ferromagnet will lose its permanent magnetic properties and become paramagnetic.
'Ferromagnet' is a noun naming the object/substance. 'Ferromagnetic' is an adjective describing the property of a material (e.g., 'Iron is ferromagnetic').
Yes. While iron is the most common, materials like nickel, cobalt, gadolinium, and some of their alloys are also ferromagnets.
