Multi-stability of a body with magnetizable elastomer in a non-uniform magnetic field

Research of the deformation of a thin body with a magnetizable elastomer in the magnetic field of a coil

“…It is possible to show that if dL/dL 0 < 0 the equilibrium state is unstable [9]. So, the middle of these three values L corresponds to the unstable equilibrium state because the dL/dL 0 < 0 at this branch of the solution.…”

“…In [6][7] the bistability of the ferrogel equilibrium shapes in a nonuniform magnetic field of an electromagnet is found experimentally. In [8][9] the possibility of bistable and of multistable equilibrium shapes of bodies with ME in different magnetic fields is shown theoretically.…”
