Item details

Neodymium magnets (from the Rare Earth magnet family) are the most powerful permanent magnets in the world and can be used in numerous applications requiring strong, compact permanent magnets.

These rod magnets (30-count) are 0.125 inch (3.2mm) diameter and 0.500 inch (12.7mm) long. They are magnetized through the length. They are composed of grade N40 neodymium iron boron magnetic material, grade N40 is stronger than N35 and N38. Some suppliers in the market use lower grades magnets for higher grades, however, we at Magnets Warehouse guarantee that our neodymium magnets come with true grades. These magnets are plated in nickel-copper-nickel for a shiny corrosion resistant finish. Maximum working temperature is 176 F (80 C).

Buyer agrees to obtain a full understanding of the risks and hazards associated with the use, handling, and transportation of the products sold here under prior to using, handling, transporting or distributing these products. Seller provides information to its customers about the hazards presented by magnetic material. This information should not be construed as complete and exhaustive information on the hazards presented by magnetic materials. Buyer is responsible for checking the accuracy, completeness, currency and/or suitability of all information themselves. Seller does not represent, guarantee or warranty the accuracy, completeness, currency, or suitability of hazard information it presents to buyers. Seller specifically disclaims any and all liability for any claims or damages that may result from providing this information. RARE EARTH MAGNETS HAVE INHERENT HIGH MAGNETIC FIELD STRENGTH. THIS HIGH FIELD STRENGTH IN CERTAIN APPLICATIONS CAN BE A HAZARD TO HEALTH, LIFE AND PROPERTY. BUYER ACKNOWLEDGES THIS AND IS SOLELY RESPONSIBLE FOR DETERMINING THE APPROPRIATE USE OF THESE MAGNETIC PRODUCTS IN THEIR APPLICATION. RARE-EARTH MAGNETS SHOULD NOT BE INGESTED OR INHALED. IMMEDIATE MEDICAL ATTENTION IS REQUIRED IF MAGNETS ARE INGESTED OR INHALED. BUYER ACKNOWLEDGES THIS AND IS SOLELY RESPONSIBLE FOR ENSURING THAT CHILDREN WILL NOT HANDLE OR HAVE ACCESS TO THE MAGNETS SOLD BY SELLER. Rare earth magnets sold by Seller are primarily composed of neodymium, dysprosium, samarium, iron, cobalt, nickel, copper and boron. The chemical, physical and toxicological properties of neodymium, samarium and dysprosium have not been thoroughly investigated and recorded. Buyer acknowledges this and is solely responsible for determining the appropriate use of these magnetic products in their application. The current Material Safety Data Sheets (MSDS) should be consulted by Buyer to obtain current procedures for handling or working with these substances in a safe manner. Neodymium-iron-boron rare-earth magnets are susceptible to oxidation. These magnets are plated to reduce their oxidation susceptibility but will oxidize in many environments. Most rare earth elements (neodymium, dysprosium, samarium, etc.) absorb hydrogen into their material structure resulting in expansion and cracking of the material which is referred to as decrepitation. Therefore, rare earth magnets are not recommended where exposure to hydrogen is likely. Buyer acknowledges this and is solely responsible for determining if these magnets are fit for a particular environment.
