PURPOSE:To clearly recognize the position of a magnetic pole even from the place aparting from the main body of a magnet as well as to obtain the multipolar magnet aggregate in which the magnetic flux of each magnetic pole works powerfully by a method wherein a complete diamagnetic member is inserted between the proximity magnetic poles. CONSTITUTION:The title multiple magnet aggregate is an aggregate of a magnet having a plurality of pairs of magnetic poles, and a complete diamagnetic member is inserted between magnetic ples or it is arranged around the magnetic pole. For example, two square pole-shaped permanent magnets 1A and 1B and three complete diamagnetic members 2A, 2B and 2C are arranged and fixed, and a multipolar magnet aggregate is formed. When this multipolar magnet aggregate is cooled down to the critical temperature or less at which the complete diamagnetic member displays a complete diamagnetic property, the greater part of the lines of magnetic force 3 are vertically emitted from the surface of the magnetic pole. As a result, the lines of magnetic force can be discriminated easily when the multipolar magnet aggregate is extended to the point aparted a long distance from the magnet.
