This paper is concerned with a description of coupled thermal stress and Maxwell stress subject to a thermal shock on the surface of a solid cylinder in an uniform magnetic field. We consider an influence of magnetic field, then it is supposed that the material property of the cylinder is a paramagnetic or ferromagnetic one which is magnetically soft, and mechanically and thermally isotropic. We analyzed mutually coupled thermal stress problems of temperature field, thermoplastic one and magnetic one theoretically. The equations and analytical results for these coupled fields are formulated theoretically, and thereafter the numerical calculations are carried out for temperature change, components of strain, thermal stress, Maxwell stress and magnetic stress in a transient state. We illustrated these numerical results for such magnetic fields, and we examine the influence of the magnetic field and an effect of a coupling parameter.
