Description: Strong Neodymium block magnets Neodymium (chemical symbol Nd) is element 60 on the periodic table. It is a rare earth metal & forms one of the Lanthanides series. When added to Iron (Fe) & Boron (B) (chemical formula Nd 14 Fe 21B) 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. Application: Smaller magnets are often used for jewellery clasps, magnetic therapy jewellery, magnetic earrings, fridge magnets, model train connectors, wargaming models, motors, science projects etc. Larger magnets are used for science projects, actuators, separators, speakers, pumps, magnetic therapy & circuit breakers in power stations. Tip:1, Strong magnets should Keep away from Ironware & some easily magnetized iron products, such as monitors, bank cards, computers, televisions, mobile phones & other.2, Strong magnets should be stored in a dry, heated environment, & need to use of plastic, wood, cardboard, foam to separated & wrapped.3, Magnets might be interested in water meter, Electric meter, gas meter & some metering equipment exist some inaccurate affect (Such as: if magnets placed near the meter, the meter will slow down) Properties: Length: 50mm (1.96)
