What is a neodymium magnet? Neodymium magnets are strong permanent magnets, and part of the Rare-Earth magnet family. They are also referred to as “NdFeB”, “Neo” or “NIB” magnets, as they are composed mainly of Neodymium (Nd), Iron (Fe) and Boron (B). (top)

Why are neodymium magnets so strong? Neodymium magnets are considered strong because they have a high saturation magnetization and resist demagnetization. Although they are more costly than ceramic magnets, strong neodymium magnets pack a powerful punch! A primary benefit is that you can use a smaller sized NdFeB magnet to achieve the same objective as a larger, less expensive magnet. This can potentially lead to a lower overall cost, as the size of the entire device can shrink.

How long do neodymium magnets last? Neodymium magnets will likely lose less than approximately 1% of their flux density over a 10-year period if their physical properties remain intact, and they are not subjected to demagnetizing influences (such as high-temperatures, opposing magnetic fields, radiation etc.).

What are the main characteristics of neodymium magnets? Neodymium magnets are far less subject to cracking & chipping and less costly than other rare-earth magnetic material such as Samarium Cobalt ("SmCo"). They are however, more sensitive to temperature. For applications where this is critical, SmCo may be the better choice, since its magnetic properties are very stable at elevated temperatures.

What are some common applications for neodymium magnets? Neodymium Magnets can be used to keep drawers closed, keep cabinet doors closed, keep expensive chef knives safe and sharp on the wall or drawer.  OR keep doors open.  Don’t you hate it when a door won’t stay open so you can put stuff away or get things out?  Magnets eliminate the stress and fight to get things done.

What are the best temperatures to use for neodymium magnets?  These magnets should not be used in temperatures above 130° C (240° F) without careful magnetic circuit design.

 Do neodymium magnets require surface treatments? Magnets that are not protected with a surface coating (such as plating) may rust in humid conditions.  OrganizedObie.com magnets are coated.

What is a permanent magnet? Permanent magnets represent the majority of magnetic materials available today. A permanent magnet is made from ferromagnetic materials, which have magnetic fields that do not turn on and off like electromagnets. We carry a large inventory of permanent neodymium magnets in a wide variety of shapes, sizes and uses.

What is a rare-earth magnet? Rare-earth magnets are the strongest type of permanent magnets available today and produce significantly stronger magnetic fields than ceramic (ferrite) or alnico magnets. There are two types of rare-earth magnets; neodymium and samarium cobalt.

How are magnets rated? Magnets are typically rated by their residual induction, coercive force & maximum energy product. This refers to the maximum strength that the magnetic material can be magnetized to.

 What does "approximate pull Info" mean? The approximate pull info listed is for reference only. These values are calculated under the assumption that the magnet will be attached to a flat, ground 1/2" thick mild steel plate. Coatings, rust, rough surfaces, and certain environmental conditions can significantly reduce the pull force. Please be sure to test the actual pull in your actual application. For critical applications, it is suggested that the pull be de-rated by a factor of 2 or more, depending on the severity of a potential failure.

What safety precautions should be taken into consideration when working with neodymium magnets? Neodymium magnets are hard, fairly brittle, and high in magnetic strength. They can snap together with great force, so please ensure that all personnel handling these magnets are aware to handle them carefully in order to avoid injuries. They can also chip or break if dropped or if snapped together, so please take special care when handling these powerful magnets!
