50pcs 4mm x 6mm N42 Strong Round Disc Magnets Rare Earth Neodymium Magnet

50pcs N42 Strong Round Disc Magnets 4mm x 6mm Rare Earth Neodymium Magnet

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.
Usually placed in room temperature, the maximum operating temperature is 80 ° C , and it never will demagnetization.

Tip:
1, Strong magnets should Keep away from Ironware and some easily magnetized iron products, ako sú monitory, bankové karty, počítačov, televízory, mobilné telefóny a iné
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, Magnety môžu ovplyvniť vodomer ,Electric meter, plynomer a niektoré meracie zariadenia majú určitý nepresný vplyv (Ako napr : if magnets placed near the meter, merač sa spomalí)

POZOR: We would not recommend this magnet be used by children under 5 without supervision!
