1. NdFeB rare earth magnets are mainly used in motors, generators, poly fitters, maesuring instruments, magnetic drives, magnetic resonnce, sensors, linearactuators, microphone assemblies, apeakers, magnetic hooks, MRI/NMR.

2. Due to the strong magnetizing, never place neodymium magnets near electronic appliances, such as cards, televisions, VCRs, computer monitors and other CRT displays.

3. Never allow neodymium magnets near a person with a pacemaker or similar medical aid. Keep the magnets away from children.

The neodymium magnets are extremely strong, and must be handled with care to avoid personal injury and damage to the magnets.

4. Some Neodymium magnets will lose their magnetic properties if heated above 175°F (80°C).

5. The magnets must be slid off/on. Neodymium magnets are brittle and prone to chipping and cracking. They do not take kindly to machining.

1. Which is the strongest type of magnet?
Neodymium (more precisely Neodymium-Iron-Boron) magnets are the strongest permanent magnets in the world.
2. What are neodymium magnets?  Are they the same as "rare earth"?
Neodymium magnets are a member of the rare earth magnet family. They are called "rare earth" because neodymium is a member of the "rare earth" elements on the periodic table. Neodymium magnets are the strongest of the rare earth magnets and are the strongest permanent magnets in the world.
3. What's the Grade of a magnet ?
Atech Neodymium Permanent Magnet are graded according to their maximum energy product, which relates to the magnetic flux output per unit volume. Higher values indicate stronger magnets and range from N35 up to N52.  and M, H, SH, UH, EH, AH series,can be customized into a wide range of shapes and sizes with precise tolerances. Multiple choices of coatings and magnetization orientations can meet specific customer requirements. Letters following the grade indicate maximum operating temperatures (often the Curie temperature), which range from M (up to 100 °C) to EH (200 °C) to AH (230 °C)
4. What materials do magnets attract?
Ferromagnetic materials are strongly attracted by a magnetic force.  The elements iron (Fe), nickel (Ni), and cobalt (Co) are the most commonly available elements. Steel is ferromagnetic because it is an alloy of iron and other metals.
5. What materials can I use to block/shield magnetic fields?
Magnetic fields cannot be blocked, only redirected. The only materials that will redirect magnetic fields are materials that are ferromagnetic (attracted to magnets), such as iron, steel (which contains iron), cobalt, and nickel. The degree of redirection is proportional to the permeability of the material. The most efficient shielding material is the 80 Nickel family, followed by the 50 Nickel family.
6. How is the strength of a magnet measured?
Gaussmeters are used to measure the magnetic field density at the surface of the magnet. This is referred to as the surface field and is measured in Gauss (or Tesla).  Pull Force Testers are used to test the holding force of a magnet that is in contact with a flat steel plate. Pull forces are measured in pounds (or kilograms).
7. Can I cut, drill, or machine neodymium magnets?
The Neodymium Iron Boron material is very hard and brittle, so machining is difficult at best.
