PURPOSE:To provide a magnetic separator where the weight of a magnetic disk is lighter than that of the conventional one without lowering adsorption efficiency of magnetic particles. CONSTITUTION:A plurality of permanent magnet fragments 30a, 30a arranged in the peripheral part of a magnetic disk 20 are arranged so that the polarity of the permanent magnet fragments opposite to each other through the void 34, 34... between magnetic disks 20, 20 may be the same. Thereby the peripheral parts of the adjacent magnetic disks 20, 20 repel each other by the magnetic field of the same polarity, causing the magnetic disk 20 to be not bent. Therefore since the rigidity of a magnetic plate 28 of the magnetic disk 20 is lower than that of the conventional one, the weight of the magnetic disk 20 is lighter than that of the conventional one without lowering adsorption efficiency. |
