A magnetic field configuration produced by immersing poloidal current rings in a toroidal magnetic field is examined, covering wide range of parameters : number of the rings, aspect ratio of the ring and amount of the ring current. Owing to the toroidal effect, null-field lines shift from their original positions in case of the linear configuration. An averaged magnetic well is certainly formed around the separatrix and also local magnetic shear appears due to the toroidal effect. Constant ∮dℓ/B surfaces close themselves, except for those far from the minor axis. Critical lines where δ∮dℓ/B=0 exist in the bad region of the torus. Cases when the current in the ring is induced by the time variation of the toroidal field are considered. Minimum B can be formed when the number of the ring exceeds a value which is given by the aspect ratio.
