Neodymium magnet (strong magnet)
Neodymium magnet standard product
Neodymium magnets create a strong magnetic field that is said to be the strongest in the world on the current market.Depending on the application, the shape can be processed into a round shape, a square shape, a ring shape, etc.Although it has excellent mechanical strength, it is surface-treated because it is easily rusted, and it is generally required to be used at 80 ° C or lower.
