Ring‑Shaped Neodymium Magnet【1-10 Pieces Per Package】

[Features]
· Neodymium magnets are the strongest magnets of all, and are ideal for reducing size and increasing the performance of devices.
· On its own, the material is weak to rust and so has been finished with a nickel plating. Thanks to the excellent rustproofing and durability properties of the plating technology, it should encounter no problems under normal usage conditions.
· Used widely in various cutting-edge fields such as in cell phones, HDDs, hybrid cars, etc.
· There is no attraction force measurement data available for the model numbers listed below. Thank you for your understanding.
[NOR001/NOR002/NOR021/NOR160/NOR244/NOR317/NOR383/NOR425]
