Neodymium magnets are the strongest type of permanent magnet currently made. They are amazingly powerful for their size and have innumerable uses. These neodymium magnets are 1/4 inch in diameter and 3/8" long. They are composed of grade 42 NdFeB material and are plated in nickel-copper-nickel for a shiny corrosion resistant finish. A special feature of this magnet is that it is magnetized through the diameter instead of the length, so the N and S poles are on the curve surfaces instead of the flat surfaces. The tolerances of all the dimensions are +/-0.01mm with coating.

CMS makes the top notch neodymium magnets with the state of the art technology. CMS neodymium magnets are superior to other brand in terms of higher strength, better coating, tighter tolerance and better longevity. All the CMS neodymium magnets are made under ISO 9002 quality systems.

Keep these neodymium magnets away from children under 5 years old. They are not edible and lethal when swallowed.

About CMS Neodymium Magnets:
CMS makes its own neodymium magnet with the state of the art technology under ISO 9002 quality system. The CMS Neodymium magnets makes the strongest neodymium magnets available. Neodymium magnets are also known as NdFeB magnets, or neo rare earth magnets. Since it's very strong, people also simply call it super strong magnets or super powerful magnets. The major elements of this magnet include neodymium (Nd), iron (Fe) and boron (B), or NdFeB.
