Neodymium magnets are made from a compound of neodymium and a ferromagnetic transition metal such as iron, with a Curie temperature well above room temperature. neodymium magnets, magnet blocks or neodymium rods, and their basic geometry is rectangular. Blocks are always used for industrial or laboratory purposes and sometimes small blocks can be used as process magnets to enjoy hours of fun.

What is the meaning of neodymium magnets?
Neodymium magnets are graded according to their maximum energy product, which is related to the magnetic flux output per unit volume. Higher values indicate stronger magnets. For sintered NdFeB magnets, there is a widely accepted international classification. They range in value from 28 to 52. The first letter N before the value is an abbreviation for neodymium, meaning sintered NdFeB magnet. The letters after the value indicate the intrinsic coercivity and the maximum working temperature (positively related to the Curie temperature), ranging from the default value (up to 80 °C or 176 °F) to TH (230 °C or 446 °F).
Neodymium magnets are anisotropic sintered magnets - the alloy is jet ground into a fine powder and then compacted in the presence of a magnetic field to give it a preferred direction of magnetization. The NdFeB magnets are then sintered to fuse the powders together, followed by final processing and magnetization to produce a complete super-strong neodymium magnet.
Neodymium magnets are also known as neodymium magnets, NdFeB magnets, NdFeB magnets, neodymium magnets, NdBFe magnets, NdFeB magnets, NIB magnets, super magnets and rare earth magnets (please note that SmCo is also known as rare earth magnets).
Neodymium magnets are also called rare earth magnets because neodymium is a rare earth element with a value of 60 in the periodic table. it is important to note that there is nothing rare about rare earth magnets - the required element is easily available and hundreds of tons of neodymium magnets are produced every year.
The neodymium magnets (NdFeB magnets) were developed 25 years ago and were first marketed in 1984. neodymium magnets were originally developed for voice coil motors in computer hard disk drives, a market that still accounts for over 50% of all neodymium magnets produced. Other applications include high performance motors, brushless DC motors, generators, magnetic separation, magnetic resonance imaging, sensors and loudspeakers. They are becoming increasingly popular in a variety of novelty products, such as refrigerator magnets and various magnetic connection gadgets for the retail market.
Shine Magnetics are capable of providing not only single magnet but also the unique combination of magnetism, experts and experience. We are also pleased to give suggestions for customers` special requirements from irregular magnets to complete systems. We can proceed to develop and test the solutions before producing the final products, working with you or on your behalf.
