       Characteristic : 
       NdFeB Super-strong magnet is the most powerful magnet in all magnet materials
       on the market.In general, in order to prevent surface oxidation,NdFeB magnets
      are nickel plated,but even if the surface is rust-proof,after a period of time
      (depending on the environment,about one year),there will still be surface oxidation.
      A phenomenon occurs.Although the surface has oxidation, it has no effect on the
                                                                                                                                             magnetic strength of the magnet itself, and it does not affect the performance.
