| Abstract: | The vibration and dynamic stability of the linear ferromagnetic beam, which is simply supported under the action of an axial force and in the transherse field, have been studied.
Under the existing edd current, a dynamic equation of beam was derived and the effects of the edd current is discussed on the dynamic characteristic of the beam. |
