Abstract: The magnetoelastic problem of a circular shell subjected to the magnetic loadings is considered. In this paper the magnetic loadings include a point magnetic source in the domain outside or inside the circular shell or a uniform magnetic induction applied at infinity. Based upon the complex variable theory and the method of analytical continuation, the solutions of magnetic field quantities and the tangential magnetoelastic stresses in the shell and its outer and inner regions are obtained. The tangential magnetoelastic stresses for a thin shell in air under different magnetic loadings are also provided and compared with some special case of which the solution can be found in the literature, which reveals that the present solution is exact and general.
