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 available. How can I identify the poles of the magnets? There are several simple methods that can be used to identify the North and South poles of neodymium magnets. 1) The easiest way is to use another magnet that is already marked. The North pole of the marked magnet will be attracted to the South pole of the unmarked magnet. 2) If you take an even number of magnets and pinch a string in the middle of the stack and dangle the magnets so they can freely rotate on the string, the North pole of the magnets will eventually settle pointing North. This actually contradicts the “opposites attract” rule of magnetism, but the naming convention of the poles is a carry over from the old d

Neodymium magnets are a member of the rare earth family and are currently the strongest permanent magnets in the world! They are composed of neodymium, iron and boron (NdFe) Q: What does the grade N35, N40, N42,N45,N48,N50 mean? A: These magnets come in a variety of grades which are measured in units millions of Gauss Oersted. Basically, the higher the grade the stronger the magnet and its pull force. Q: What does pulling force mean? A: Pulling force is a measure of magnetic strength. It is the amount of force required to remove a magnet parallel to a solid magnetic surface, such as a steel plate. Q: How are these magnets polarized?. A: Through Thickness. Q: Do I have to worry about temperature with neodynium magnets? A: Yes. They are sensitive to heat so do not heat them above 175°F (80°C) If you do, they will begin to lose their magnetic strength. This normally applies only to industrial usage of heating the magnets, normal application will not affect the strength of the magnets. Q:

Neodymium magnets are a type of permanent magnets which are known as rare earth magnets, due to the fact that they contain one or more of the rare earth elements of the periodic table. Most neodymium magnets are made of a metal alloy containing neodymium, iron, and boron. They are much stronger than most of the magnets we are accustomed to using, like refrigerator magnets. Because of the forces they generate, these magnets can be dangerous or even cause fatal injury if not handled properly. Neodymium magnets are the strongest permanent magnets available, and are able, in some cases, to hold up more than 1,000 times their own weight. They are manufactured in many different shapes and sizes, such as cubes, discs, spheres, plates, and rings, among others. Small magnets of this type are used in certain electronic devices, such as computer hard drives and headphones. They have also been found to be useful in the construction of engines for remote-controlled model aircraft. The strength of n

Neodymium magnets are a type of rare earth magnet. They are the strongest rare earth magnets and can be very dangerous if handled improperly. They are often referred to as rare earth magnets because they belong to the rare earth elements on the periodic table. But they are not the same as rare earth magnets. There are different types of rare earth magnets and Neodymium magnets are just one type. Neodymium magnets are the strongest permanent magnets available today. Neodymium magnets are also known as Neodymium-Iron-Boron or Nd-Fe-B or NIB super magnets since they are composed of these elements. These magnets are extremely strong for their small size and are metallic in appearance.
