[mag-nee-toh-strik-shuh n] /mægˌni toʊˈstrɪk ʃən/
a change in dimensions exhibited by ferromagnetic materials when subjected to a magnetic field.
a change in dimensions of a ferromagnetic material that is subjected to a magnetic field
The change in shape and density of a substance, especially a ferromagnetic substance, when exposed to a magnetic field. The change depends on the direction and strength of the magnetic field. Rapid, alternating magnetostriction causes the iron cores of household transformers, which are subject to a changing magnetic field, to hum or buzz.
- Magnetostrictive delay line
storage, history An early storage device that used tensioned wires of nickel alloy carrying longitudinal waves produced and detected electromagnetically. They had better storage behaviour than mercury delay lines. [H. Epstein and O.B. Stram, “A High Performance Magnetostriction-Sonic Delay Line,” Transactions, Institute of Radio Engineers, Professional Group on Ultrasonic Engineering, 1957, pp. 1-24]. (2002-11-08)
