FAQ

1. 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.

2. What are neodymium magnets made from and how are they made?
Neodymium magnets are actually composed of neodymium, iron and boron (they are also referred to as NIB or NdFeB magnets). The powdered mixture is pressed under great pressure into molds.
The material is then sintered (heated under a vacuum), cooled, and then ground or sliced into the desired shape. Coatings are then applied if required.
Finally, the blank magnets are magnetized by exposing them to a very powerful magnetic field(magnetizier) in excess of 30 KOe.

3. Which is the strongest type of magnet?
N54 neodymium (more precisely Neodymium-Iron-Boron) magnets are the strongest permanent magnets of N series (working temperature must be under 80° ) in the world.

4. 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).

5. How is the attraction force of each magnet determined?
All of the attraction force values we have on the data sheet were tested in the factory laboratory. we test these magnets in case A situation.
Case A is the maximum pull force generated between a single magnet and a thick, ground, flat steel plate with ideal surface, perpendicular to the pulling face.
The real effective attraction/pull force may vary much according to the real situations, such as the angle of contact surface of the two objects, the metal surface coating, etc.
