特性を得ることができる効果がある。 As already explained, the desired magnet is assembled as a set of small magnets of various shapes and adhesive.
Gather small magnets that suit the intended use of the magnets, fill the gap formed by them with a high-containing magnetically conductive adhesive,
By embedding and fixing small magnets, it is possible to obtain a magnet with a desired shape. One magnet, which is an assembly of small magnets, can be easily dismantled when unnecessary and used as an assembly for magnets of other shapes. In this way, magnet molded bodies, which were previously difficult to form, can be molded into any shape by collective filling formation of small magnets, and solid magnets can be easily obtained, and the magnetic properties are better than those of conventional solid magnets. It has the effect of obtaining magnetic properties similar to those of the body.
