像管用多極電磁石装置。[Claims for Utility Model Registration] (1) A device for generating a multipolar magnetic field within the neck portion of a picture tube, which includes a ferromagnetic material disposed outside the neck portion in a direction that goes around the outer periphery of the neck portion. a plurality of pole pieces arranged at intervals around the neck portion in close proximity to or in contact with the substrate core; and a facing surface or a contact surface between the substrate core and the pole piece. A multipole electromagnet device for a picture tube, comprising a flat coil wound so as to surround the neck portion and having a winding surface substantially in a plane perpendicular to the axis of the neck portion. (2) A multipolar electromagnet device for a picture tube according to claim 1, in which a coil is sandwiched between a substrate core and a pole piece. (3) The multipole electromagnet device for a picture tube according to claim 2, wherein a projection is provided on one of the substrate core and the pole piece to bring them into contact, and a coil is fitted into the projection. (4) The multipole electromagnet device for a picture tube according to claim 1, wherein the substrate core and the pole piece are in close contact with each other in a plane, and the coil is slightly bent in the thickness direction at the inner portion.
