There are two types of rare earth magnets available: Neodymium and Samarium Cobalt.They are called rare earth because their composition elements found in the "Rare Earth" or Lanthanides portion of the Periodic Table of Elements.Neodymium magnets (Nd-Fe-B) are composed of neodymium, iron, boron and a few transition metals. Samarium cobalt magnets (SmCo) are composed of samarium, cobalt and iron. Th...

N35, N38, N42, N38SH...what does it all mean? Neodymium magnets are all graded by the material they are made of. As a very general rule, the higher the grade (the number following the 'N'), the stronger the magnet. The highest grade of neodymium magnet currently available is N50. Any letter following the grade refers to the temperature rating of the magnet. If there are no letters following the gr...

The coatings do not affect the magnetic strength or performance of the magnet.Neodymium magnets are a composition of mostly Neodymium, Iron and Boron. If left exposed to the elements, the iron in the magnet will rust. To protect the magnet from corrosion and to strengthen the brittle magnet material, it is usually preferable for the magnet to be coated. There are a variety of options for coatings,...

The term Rare Earth Magnets is used to refer to a group of magnetic materials whose alloys consist of one or more of the Rare Earth elements. These materials are characterized by exceptionally strong magnetic properties.

Some magnets, called oriented or anisotropic magnets, have a preferred direction in which they should be magnetized. The "orientation direction," also known as an "easy axis" or "axis," is the direction that achieves its maximum magnetism. Other magnets, called unoriented or isotropic magnets, can be magnetized in any direction.

All magnets have points, or poles, where their magnetic strength is concentrated. Those points are called poles. We label them north and south because suspended magnets orient along north-south planes. On different magnets, like poles repel each other, opposite poles attract. Are permanent magnets really permanent?

Several factors can weaken the magnetism in a magnet. If a magnet is stored close to heat, strong electrical currents, other magnets, or radiation, it can lose its strength. Additionally, high humidity can corrode neodymium magnets. DemagnetizationRare Earth magnets have a high resistance to demagnetization, unlike most other types of magnets. They will not lose their magnetization around other ma...

That depends on how the magnetism was lost. Usually magnets can regain their original strength unless theyve been exposed to extreme heat.

In general, magnetic field attenuation is a function of the permeability of the material. A better shielding material has high permeability per weight. For metallic foil and sheet, the most efficient shielding material is the 80 Nickel family (e.g., Molypermalloy), followed by the 50 Nickel alloys (e.g., Deltamax). The economical silicon-steel foils and sheets are also good shielding material when...

According to the United States Department of Transportation and the Office of Hazardous Materials Safety, it is against regulations to ship a magnet by air that maintains a field of more than 0.00525 gauss measured at 4.5 meters (15 feet) from any surface of the package. This is to prevent the magnet from interfering with the operation of the aircraft's navigational compass. There are no federal ...

Once a magnet is fully magnetized, it cannot be made any stronger.

If the magnets are not subjected to external magnetic fields high enough to cause demagnetization - and/or - elevated temperatures above the advertised maximum use temperature the field will remain at or near as received. This could be expected last for the life of the application.

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㡯s maximum operating temperature.

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.

Magnets affect electrically charged particles and electrical conductors. Magnets have the ability transform electrical energy without losing their own energy. These effects can perform useful functions, for example: Electrical-to-mechanical effects are key in the function of motors, loudspeakers, and equipment that requires charged particle deflection. Mechanical-to-electrical effects are usef...
