N42 Magnets

Neodymium Magnets: The Most Powerful Magnets Available

Neodymium magnets, a member of the rare earth magnet family, are the strongest permanent magnets available. They are also known as NdFeB magnets, referring to their composition of neodymium (Nd), iron (Fe), and boron (B). These strong magnets offer a high resistance to demagnetization, and offer a strong resistance to heat. Standard neodymium magnets have a maximum operating temperature of 180 °F, and high-temperature neodymium magnets can withstand temperatures up to 300 °F. Neodymium magnets are typically coated with nickel in order to protect the magnet from corrosion and strengthen the brittle magnetic material. Other coatings are available, including zinc, tin, copper, epoxy, silver, and gold.

Diverse Stock of N42 Neodymium Magnets for Power in Any Shape or Size

Bunting-Elk Grove Village offers several different varieties of N42 neodymium magnets. Grade N42 magnets have a maximum energy product of 42MGOe. If a magnet has a higher grade, it is a stronger magnet. Currently, neodymium magnets range from grades N35 to N55. If you are seeking a higher grade of magnet, BuyMagnets also stocks N52 neodymium magnets here—the strongest magnet we currently have available. N42 neodymium magnets have a diverse range of applications, and deliver high power in a small package.

BuyMagnets.com has eight standard designs of N42 neodymium magnets in stock—with hundreds of variations within these design categories. We offer plated N42 neodymium disc magnets with or without an adhesive backing, plated N42 neodymium block magnets, countersunk ring and block N42 neodymium magnets, and countersunk N42 neodymium pot magnets in both BN6 and BNA series.

Safety Precautions for Rare Earth Magnets

Due to how powerful these rare earth magnets are, it is important to take safety precautions when using neodymium magnets. Because these are the strongest magnets available, they can cause damage to electronic devices (including credit cards and essential medical devices, such as pacemakers), and should not be placed near them. Fingers and hands may be severely pinched if they are in the path of two attracting magnets. Strong magnets, such as neodymium magnets and other rare earth magnets, are NOT toys, and must be kept out of the reach of children.
