Block neodymium magnets are usually coated Nickel-Copper-Nickel plating to prevent the iron from rusting.
Neodymium block magnet was made of NdFeB, has strong magnetic performances and appearance does not rust, usually placed in room temperature, the maximum operating temperature is 80 ° C, and it never will demagnetization.
In spite of their strength, these magnets are extremely lightweight, which explains their popularity in various and diverse applications and products. Interesting to note, without these super-strong rare earth magnets many of the technological advances that have taken place over the past few decades would not have been possible!
In Conclusion, Neodymium Block magnets are strong… Most noteworthy these magnets must be handled with care, the stronger magnetic fields can be hazardous therefore must be handled carefully:
