magnetostriction
Very lowTechnical/scientific
Definition
Meaning
The property of ferromagnetic materials to change shape or dimensions when subjected to a magnetic field.
The phenomenon where magnetic materials undergo mechanical deformation under magnetization, and conversely, where mechanical stress can alter their magnetic properties.
Linguistics
Semantic Notes
A compound noun formed from 'magneto-' (relating to magnetism) and 'striction' (from Latin 'strictio' meaning drawing tight). Used exclusively in physics, materials science, and engineering contexts.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'магнитное напряжение' (magnetic tension) which is different.
- Correct translation: 'магнитострикция' (direct cognate).
Common Mistakes
- Misspelling as 'magnetorestriction' or 'magnetostriction'.
- Confusing with 'piezoelectricity' (electricity from pressure) or 'electrostriction' (deformation from electric field).

FAQ
Frequently Asked Questions
It's used in ultrasonic transducers, sonar devices, precision actuators, sensors, and vibration generators.
James Prescott Joule discovered the effect in nickel and iron in the 1840s.
Yes, the effect is generally reversible; removing the magnetic field typically returns the material to its original shape.
Ferromagnetic materials like iron, nickel, cobalt, and certain rare-earth alloys (e.g., Terfenol-D) show this property.
