Summary of the invention
The technical problem that the present invention solves is, for the above-mentioned deficiency of prior art, proposes a kind of orientation fully and all uniform radiation ring magnet aligning device of all directions orientation.
The technical scheme that technical solution problem of the present invention adopts proposes a kind of radiation ring magnet aligning device, it comprises the column plug as internal magnetic pole, for placing the annular die cavity of magnetic, the magnetic field generation device being arranged at column plug opposite end side and the outer magnetic pole rotated around annular die cavity; Described column plug is through annular die cavity, and described relative magnetic field generation device produces homopolar field and makes to produce radiation field around column plug.
Further, described magnetic field generation device be electromagnetic generating device, the generation device that is combined with permanent magnetism of permanent magnetism generation device or electromagnetism.
Further, described internal magnetic pole is contrary with the magnetic pole of outer magnetic pole.
Further, described outer magnetic pole thickness is equal to or greater than described annular die cavity thickness, described outer magnetic pole towards the end face of annular die cavity in the arc caved inward.
Further, described outer magnetic pole is less than 1/8 annular die cavity girth towards the arc length of the end face of annular die cavity.
