Disclosed in the present invention are a magnet assembly and a preparation method therefor. The magnet assembly is formed by overlapping and adhesively bonding a plurality of magnetic sheets which are made of a rare earth permanent magnet material; adhesive layers are provided between the magnetic sheets; each adhesive layer comprises epoxy resin glue and irregular-shaped particles evenly distributed in the epoxy resin glue; the thickness of each adhesive layer is 80-200 μm; and the preparation method comprises the steps of glue mixing, glue dispensing, pressurizing, baking and the like. By adding irregular-shaped particles to the adhesive layers, the magnet assembly and the preparation method of the present invention greatly improve the thickness uniformity of the adhesive layers, improving the performance of the magnet assembly.
