Abstract
The refined theory of magnetoelastic beam and the refined theory of beam on Winkler Foundation are connected. Using the Lur'e method and linear magnetoelastic general solution, expressions are obtained for all the displacements, stress components and perturbation of magnetic intensity in term of the midline displacement, its derivatives and the midline perturbation of magnetic intensity. The equations of refined theory are given from the Winkler Foundation's boundary conditions and magnetic boundary conditions. At last, the stress components are decomposed into two parts: symmetry part and antisymmetry part. From the antisymmetry part of the stress components, the deflection control equation is obtained, and the symmetry part of the stress components is further decomposed into three parts.
