路 Rare earth magnets are the strongest type of permanent magnet currently made. They are amazingly powerful for their size and have innumerable uses. 路 They are magnetized through the thickness. They are composed of neodymium iron boron magnetic material and are plated in nickel-copper-nickel for a shiny corrosion resistant finish. Maximum working temperature is 176 F (80 C). 路 These Neodymium thin rectangular magnets provide an astonishing pull of 18lb and every magnet has a triple coating of nickel, copper and nickel again to prevent against corrosion. These Neodymium magnets are commonly used in creative applications such as model making, theatre design, furniture making, exhibition displays and packaging, magnet testers They also have many uses in engineering and manufacturing where small size and maximum strength are required. What's more, because of their resistance to demagnetization they are ideal for creating a shock-absorbing or damping effect when used to repel other magnets.
Can you test silver with a magnet? Silver is not magnetic. If you place a strong, rare-earth magnet called a Neodymium magnet on a silver coin or bar, it should not easily stick to it. If you are testing bars, you can angle one at 45 degrees and let the magnet slide down. ... If it sticks or it slides very quickly, it is not silver. Learn how to test copper and silver coins in details - they BOTH diamagnetic and behave very similar ! P.S.
