Decrypt NdFeB Magnets

Decrypt NdFeB Magnets - The formation of a magnetic field is a magnetic field generated by a molecular ring current of a magnetic substance, and the direction of movement of atoms or ions outside the nuclear electrons is random, so a large number of atom synthesis current is zero, no magnetic field, such as ferric [...]

NdFeB Plating Difficulties

NdFeB Plating Difficulties 1.The chemical activity in the material is extremely strong Neodymium iron boron parts even when in contact with water will produce hydrogen and corrosion,so: ①The use of acid and alkali before plating treatment should not be too strong, otherwise the material matrix is susceptible to corrosion, and the reaction between chlorine and [...]

Magnet Temperature Effects

Magnet Temperature Effects Magnetic properties of all the permanent materials change with temperature. Remanence, and thus the magnetic flux a magnet produces, decreases in all magnetic materials with increasing temperature. Ultimately, at certain, for each material characteristic temperature the material becomes non-magnetic. This temperature is known as Curie temperature (Tc). Figure 1 illustrates the temperature [...]

Magnet Wind Turbine Application

Magnet Wind Turbine Application Wind turbines working environment is very bad, it must be able to withstand heat, cold, wind, humidity and even salt spray test. Design life of the wind turbine is generally two years. At present, both small wind turbine or a megawatt-class wind turbines are mostly optional permanent magnet NdFeB magnets, therefore, [...]

NdFeB Rare Earth Magnets

NdFeB Rare Earth Magnets - Neodymium Magnets (Nd-Fe-B) Overview Neodymium Magnets (Neodymium Iron Boron Magnets), also known as NdFeB, NIB, or Neo magnets, are the most widely-used type of rare-earth magnet. It is the strongest type of permanent magnet made from an alloy of Neodymium, Iron, and Boron with the Nd2Fe14B tetragonal crystalline structure. It [...]

Magnet Applications

Magnet Applications, magnets for Speaker, Motor, Toy, Sensor, Switch Speaker magnets are important components in speakers Majority of speaker magnets are made from ferrites, the cost is 10 times less than NdFeB magnets.

Are Neo Magnets and NdFeB Magnets the Same?

Are Neo Magnets and NdFeB Magnets the Same? - We occasionally get inquiries and manufacturing prints identifying a custom magnet shape using the abbreviation Neo. Because shorthand works – both internally and in discussions with our customers – we likewise sometimes refer to a Neodymium magnet as Neo or NdFeB. Of the rare earth element [...]

Magnet Machining Process

Magnet Machining Process Magnet Machining Process - Magnets that have been through the sintering process are machined and plated. Machining Due to shrinkage from the sintering process, required measurements are achieved by grinding the magnets with abrasives. Diamond abrasives are used for this process because the magnet is very hard. machining Surface Treatment (Plating) [...]

How grade choice affects performance when the NdFeB magnet is subjected to heat

It is possible to demagnetise a Neodymium magnet by applying an external magnetic field in a direction opposite to the direction of magnetisation (DoM) of the NdFeB magnet. The extent of demagnetisation is a function of the total magnetic circuit (and hence the Intrinsic working point), the temperature (and hence the actual BH curve shape [...]

How a magnet is demagnetised by applying an external magnetic field

For note, the effects of temperature and external demagnetising fields are easiest to calculate on NdFeB magnets that may be demagnetised as a result of such exposure if cgs units are used (Gauss, Tesla, MGOe) as cgs units allow faster production of new BH curves. When a new Intrinsic BH curve for Neodymium has been [...]
