The invention discloses a magnetic resistance hinge. The magnetic resistance hinge comprises a left blade, a right blade and a hinged shaft, wherein the left blade is hinged with the right blade through the hinged shaft, and is provided with a left magnet; the right blade is provided with a right magnet; the polarity of the left outer end face of the left magnet is the same as that of the right outer end face of the right magnet; the left magnet arranged on the left blade is formed by a plurality of rows of magnets; and the right magnet arranged on the right blade is formed by a plurality of rows of magnets. Magnetic repulsive force generated by the left magnet and the right magnet is used for preventing a wind-blown door from rotating quickly, so that the closing speed of the door which is blown by wind is reduced effectively, and the wind-blown door is prevented from being quickly rotated and closed so as not to clamp children or the old; and simultaneously, magnetic resistance hinges with different magnetic resistance are provided according to different magnetic resistance requirements of different floors.
