Neodymium magnet (NdFeB), commonly known as "rare earth" magnet, is a high-performance permanent magnet made of neodymium, iron and boron alloys.
They are real permanent magnets and will not lose their magnetism unless heated to a temperature exceeding the maximum operating temperature rating or their protective coating is damaged.
Characteristic:
-Energy products may exceed 50mgoe
-Low corrosion resistance
