About Neodymium Magnets:Neodymium Iron Boron (NdFeB) magnets are composed of Nd, Fe, B, Dy, Co and other minor elements. They have excellent magnetic property and are extremely strong for their small size. NdFeB magnets are permanent, and have a high maximum energy product. Over the last 10 years, due to high ratio of performance over price, the NdFeB magnet has become extremely popular in almost all technology applications that require high performance magnets such as motors, sensors, computers, communications, medical equipment, meters, home appliances and so on.
Tip:1, Strong magnets should Keep away from Ironware and some easily magnetized iron products, such as monitors, bank cards, computers, televisions, mobile phones and other.
2, Strong magnets should be stored in a dry, heated environment, and need to use of plastic, wood, cardboard, foam to separated and wrapped.
3, Magnets might affect water meter ,electric meter, gas meter and some metering equipment exist some inaccurate affect (Such as : if magnets placed near the meter, the meter will slow down).
Note: Be careful fragile and clip hand, placed in a dry place, stored at room temperature!
WARNING: We would not recommend this magnet be used by children under 5 without supervision!
