Dipole magnets, driven by permanent magnet (NdFeB or SmCo) blocks rather than a coil, resulting in low environmental impact due to zero energy consumption. While the potential advantages are great, the practicalities of manufacture and use pose some significant challenges.
Permanent magnets have strong magnetic force, which causes strong attraction and repelling forces occur when they are brought close to iron objects or themselves. Magnets are difficult to handle and position.
It is therefore essential in the production of dipole magnets that the magnets are assembled safely without damaging the block or the assembler.
