Scientific definitions for magnetostriction
[ măg-nē′tō-strĭk′shən ]
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.
