Neodymium Magnets

The Most Powerful Magnets Available Today!

Buy magnets today! MagnetShop.com carries a large inventory of Neodymium magnets in various shapes and sizes, and we also custom manufacture these to fit our customer's specifications. Neodymium magnets (“Neo” magnets) are a type of Rare Earth Magnet with the highest magnetic properties, and the most powerful commercially available magnets today. Used in both consumer and technical applications, these strong magnets are excellent for craft & model making projects, high-performance motors, jewelry clasps, audio equipment, POP displays, science projects, DIY projects, hanging artwork & much more. See below for more detailed information about Neo magnets and their features & characteristics.

Features & Characteristics of Neodymium Magnets

► Characteristics: Neodymium magnets are far less subject to cracking & chipping and less costly than the other the Rare Earth magnetic material, Samarium Cobalt ("SmCo").  Neodymium is more sensitive to temperature - where this is critical, SmCo may be the better choice, since its magnetic properties are very stable at elevated temperatures.  Although Neodymium magnets are more costly than ceramic magnets, these super strong magnets pack a powerful punch! With Neodymium magnets, you can use a smaller magnet to achieve the same objective, potentially leading to a lower overall cost as the size of the entire device can shrink. (top)

► Grades & Shapes: Grades 30-52 of Neodymium magnets are available in disc, rectangle, square and rod shapes, and can be custom manufactured to meet your specialty requirements.  Just let us know what you are looking for by clicking on the Special Request icon at the top of the site. (top) 

► Common Applications: Neodymium Magnets are used in many industries for applications such as audio equipment (microphones, headphones, and loudspeakers) hard disk drives, pumps, bearings, MRI scanners, electric vehicles, wind generators, high performance motors, actuators, magnetic therapy, anti-lock braking systems, levitation devices, door latches, model making, arts & crafts, home improvement (DIY-fixing furniture, hanging pictures etc.) POP displays & more. (top)

► Temperature Stability: Neodymium magnets should not be used in temperatures above 130° C (240° F) without careful magnetic circuit design - please discuss your application with our engineers if you plan on using these magnets above this temperature. (top)

► Surface Treatments: Neodymium magnets that are not protected with a surface coating (such as plating) may rust in humid conditions. (top)

► Bonding Applications: Neodymium magnets are often assembled into products using “super glues” such as Loctite 325- as with all bonding applications, always ensure that bonding surfaces are clean and dry prior to bonding for best results. (top)

► Approximate Pull Info: The Approximate Pulls listed for Neodymium magnets are 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, and 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. (top)

► Safety Precautions: Neodymium magnets are hard and fairly brittle, and have a very high magnetic strength – these powerful magnets can snap together with great force - please ensure that all personnel handling these magnets are aware to handle them carefully to avoid injury.  They can chip or break if dropped or if snapped together - so take special care when handling these powerful magnets!
