(chemical symbol Nd) is element 60 on the periodic table. It is a rare
earth metal and forms one of the Lanthanides series. When added to Iron
(Fe) and Boron (B) (chemical formula Nd14Fe21B) the resultant magnets
are the strongest magnets currently available. Neodymium Magnets are
sometimes known as Neo, Neod or NIB magnets.

Neodymium Magnet are usually coated Nickel-Copper-Nickel plating to prevent the iron from rusting.

Block Magnet  was made of  NdFeB, have strong magnetic performances and
appearance does not rust, usually placed in room temperature, the
maximum  operating temperature is 80 ° C , and it never will

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. 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)
3. These magnets are very powerful which should be handled with great care. Without parents supervised do not allow children to playing magnets as they could get injured. Especially pay attention to the small magnets , please place in somewhere children can't reach place.

Notice: The Seller will not be held liable for any damage or injury caused by these magnets.
Safety Warning about handling neodymium magnets  
1. Handling strong magnets in a proper manner is necessary to prevent personal injury and property damage, which include magnet damage.  
2. These magnets are not toys. Please do not give neodymium magnets to children under 3 years old. Small magnets pose a choking hazard, and can be lethal if swallowed. In addition, large magnets can easily pinch fingers. So always supervise children when playing with magnets and be sure they are aware of the dangers involved.  
3. Please keep magnets away from people who are wearing pacemakers or other medical devices. These magnets could also damage CRT monitors and TV's.  
 4. It is recommended to wear gloves when handling magnets.  
5. Always handle magnets individually. Do not handle multiple magnets at the same time unless they are widely separated or stacked together.  
 6. When placing magnets together, place a spacing material between them such as a piece of plastic, wood or cardboard so that they are easy to separate when needed.  
 7. Maintain a distance of at least 3 feet from other magnets or magnetically susceptible items when handling the magnets. Pay particular attention to scissors, knives, screw drivers or any other sharp metal objects.  
 8. To separate one magnet from the others, place them on a durable non-metal surface with the magnet-to-be-separated hanging off the edge of the table. Use one hand to firmly hold the other magnets on the table, especially those closest to the magnet being separated. Use the other hand to firmly hold the magnet you are separating. Push it down and away from the other magnets, until a magnetic attraction is no longer felt. Keep the separated magnets a safe distance from each other.
