In some injuries, such as those happen in the battle field, part of shells or foreign objects that may include magnetic materials remain in victims body. In this research we calculate the torque and translational force for specific ferromagnetic objects. Translational force reaches its maximum value near the opening to the bore. Near the isocenter, however, there is no translational force acting on the ferromagnetic spherical object. For a long cylindrical shell, such as a niddle, or for a flat cylindrical shell, like a disk, the torque inside the bore is quite significant. Torque can be managed by a prior knowledge about the object orientation from an auxiliary imaging modality.
