Magneto‐sensitive elastomers are materials that rapidly and reversibly change their mechanical and magnetic properties in response to the application of a magnetic field. Typically, the magneto‐mechanical coupling is achieved and optimized by mixing, during the vulcanization process, nano or micron‐sized magnetizable particles with high magnetic saturation within a soft and highly elastic elastomeric matrix. Preferred materials are gels, resin, natural rubber, silicone rubber and nitrile rubber. The particles of choice are spherical or irregularly shaped carbonyl iron particles because of their high permeability, low remanent magnetization and high saturation magnetization. In this paper we provide an overview of different ways in which the equations of mechanical equilibrium of magneto‐sensitive materials can be written in the presence of magneto‐mechanical interactions.
