Common applications
DC and servo motors • Linear actuators • Magnetic separators • Speakers • Microphone assemblies • Sensors

Please use caution when handling magnetized neodymium magnets, their exceptional magnetic force may cause them to attract to metal (or to each other) so strongly that fingers in their path could prove painful.

Machining and tolerances
Neodymium (we like to just call it Neo) is easily ground, although coolants must be used in the process to avoid spontaneous combustion of powder. Grinding should be completed before coating or plating is applied to protect the magnets from corrosion. Standard tolerances for neodymium magnets are +/-.005” for ground dimensions.

Some magnet suppliers import unlicensed neodymium material, violating U.S. trade and import regulations. Adams Magnetic Products sells only licensed materials to meet your magnetic requirements. We are in complete compliance with holders of United States patents and the International Trade Commission requirements pertaining to imported neodymium magnets.

Temperature constraints
The temperature coefficient of neodymium has triggered several grades to be developed to meet specific operating requirements. Please refer to our chart of magnetic properties to compare the characteristics of each grade. Before choosing a neodymium magnet be sure to consider your application’s maximum operating temperature.

Magnetization
Neodymium magnets require extremely high magnetizing fields and particular consideration must be given to this when designing complex assemblies. Neodymium can be magnetized in any direction as long as it is aligned properly. In some instances multiple pole magnetization is not possible; when it is possible, special fixtures are required.

Added value services
Our knowledgeable engineering department is always available to assist in determining the best grade and size of neodymium magnet for your application. We also offer coating and plating choices for magnets we custom-machine.
