The magnetomechanical effect is a fundamental feature of ferromagnetism. The fact that the application of external stresses alters the flux density of a magnetized ferromagnet, and thus the shape, and size of its hysteresis loops is easily changeable.

Simply, it is the phenomenon of changing the magnetic properties of ferromagnetic materials by applying external stresses.

Magnetomechanical effects connect magnetic, mechanical and electric phenomena in solid materials.

  • Magnetostriction, also known as “Joule magnetostriction”, is the few parts per million change in the length of a ferromagnetic rod upon magnetization.[1]: 627 
  • Inverse magnetostrictive effect
  • Wiedemann effect
  • Matteucci effect
  • Guillemin effect names the result of a strong magnetic field on a material’s response to mechanical stress. It was first reported by Guillemin[2] in 1846 in the specific form of the change in the deflection of an iron cantilever when subjected to a coaxial magnetic field. It was later generalized and called the effect.[1] Longitudinal current can cause a similar change in deflection.[3]

Magnetostriction is thermodynamically opposite to inverse magnetostriction effect. The same situation occurs for Wiedemann and Matteuci effects.

For magnetic, mechanical and electric phenomena in fluids see Magnetohydrodynamics and Electrohydrodynamics.
