These Powerful Neodymium Cube Magnets are magnetized through their thickness, so the strong North/South poles are located on opposite sides of the cube. After experimenting with them, you will get a feel for which two sides have the strong poles.
Neodymium (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 magnets are usually coated Nickel-Copper-Nickel plating to prevent the iron from rusting.
Neodymium 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 demagnetization.
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)
To realize the better effect of waterproof and resist abrasion, Bearheart magnetics also developed out plastic coated magnets or plastic wrapped magnets. That makes neodymium magnets with plastic coated. The plastic coat is hard and not use to broke, it can protect the coated magnets better from damage. Plastic coated magnets are better waterproof magnets. Compared with rubber coated magnets, there are more colors available for plastic coated magnets. So plastic coated magnets look more beautiful than rubber coated magnets.
Today, MPCO magnetics can bulk produce plastic coated magnets, our plastic coated magnets are available on plastic coated disc magnets, plastic coated block magnets, plastic coated ring magnets….. all the magnets highly appraised by all customers. As professional plastic coated magnets producer, we now have broad sizes range for plastic coated neodymium magnets.We wish to supply plastic coated neodymium magnets and plastic wrapped neodymium magnets to more and more clients. And to be their first choice of plastic coated magnets supplier
Neodymium magnets are extremely powerful. Crushing and bruising injuries can occur when handling these magnets, especially the larger ones. When two magnets collide together, small pieces can be broken off and cause injury. For these reasons the magnets should be handled carefully and they should definitely not be allowed to crash into one another from a distance. Magnets should never land in childrens hands because swallowing them can lead to serious medical problems.
Particularly the larger neodymium magnets should never be stored or used near devices or objects that can be damaged by magnetism. This can include, among others, televisions and monitors, credit cards, bankcards, computers, data storage devices of all kinds, video and music cassettes, mechanical clocks and speakers. A large magnet can also disturb heart pacemakers. When in doubt you should exercise caution!
This powerful neodymium cube magnet measures 1-1/4″ on its sides and is made of a grade N42 neodymium, iron, and boron magnetic alloy blend. This magnetic blend is patent licensed and made under the ISO 9001 quality control systems and are plated in a nickel-copper-nickel triple layer coating for a shiny corrosion resistant finish. This magnet is great for holding purposes such as holding objects to magnetic surfaces. Moreover, this magnet is versatile and robust; applications range from industrial use to personal projects.
Please note that all neodymium rare earth magnets are fragile and require extreme caution when handling due to their brittle nature and to avoid injury due to pinching.
