Inverse magnetostrictive effect

The inverse magnetostrictive effect, magnetoelastic effect or Villari effect, after its discoverer Emilio Villari, is the change of the magnetic susceptibility of a material when subjected to a mechanical stress. == Explanation == The magnetostriction λ {\displaystyle \lambda } characterizes the shape change of a ferromagnetic material during magnetization, whereas the inverse magnetostrictive effect characterizes the change of sample magnetization M {\displaystyle M} (for given magnetizing field strength H {\displaystyle H} ) when mechanical stresses σ {\displaystyle \sigma } are applied to the sample.
