Handling Neodymium Magnets Safety Precaution With high intrinsic coercive force (Hci) over 12,000 Oe and maximum energy product ((BH)max) between 27-52 MGOe, neodymium magnets have the greatest strength among all available permanent magnet materials (>7 times stronger than ceramic magnets) as they are extremely resistant to demagnetization and have high saturation of magnetization. The magnetization [...]
Select Material Grades for Neodymium Magnets When you are trying to figure out which neodymium magnets to select for your design needs, you would always see the term “grade” or “N rating” from any supplier or manufacturer. Besides a few other criteria, desired material grade must be defined for a neodymium magnet. So, what does [...]
B-H Curve for Permanent Magnets What is a B-H curve first of all? B is the nomenclature for magnetic flux density (induction) and H is magnetic field strength; a B-H curve plots out the relationship between them for a particular ferromagnetic material. The changes in magnetic flux density is dependent on the magnetic field strength. [...]
Compression Bonded Moulded NdFeB Magnet Compression bonded magnets are composed of a special form of NdFeB powder with adhesive and using compression molding techniques in simple tools, it can be quickly machined into complex shapes. Since its materials are isotropic, bonded NdFeB magnet can be magnetized in any direction or with multiple poles. Special magnetizing [...]
Large Undulator Neodymium Permanent Magnets China MPCO MAGNETICS has some customers, who request permanent magnets for undulator, like N50M neodymium arc magnets in large sizes, with cutted sides, Nickel coating, working temperature 80 ℃. Customers usually send us drawings with enough information. A few of them require spread of magnetization less than 0.5%. As for [...]
Hast Neodymium Magnet Manufacturer – MPCO MAGNETICS Compared with traditional sintered neodymium iron boron magnets , HAST NdFeB magnets are more superior in corrosion resistance without the protection of plating. MPCO customizes HAST neodymium magnets like N38SHT, N35H HAST, N38H HAST as per customer’s special demands and applications. “HAST” is short for “Highly Accelerated Temperature/Humidity [...]
Major Difference Between Permanent Magnet & Electromagnet The major difference between an permanent magnet and electromagnet is that the former can have a magnetic field when electric current flows through it and disappears when the flow of the current stops. On the other hand, a permanent magnets are made up of magnetic material that is [...]
NdFeB Magnetic Therapy Effect 1、 Magnetized water in history Magnetic force is one of the four basic forces in nature. The compass, one of the four great inventions in ancient China, is an example of the ingenious application of magnetic force. Li Shizhen, a medical expert in Ming Dynasty, has found that the water treated [...]

When designing an application that uses magnets or electromagnets – we can help your company. Magnets R&D Magnetic design and magnetic [...]
Magnetic Design Redesign Cost One of the most important aspects of magnetic design optimizing, is being able to design to cost. Magnets are used for their magnetic properties and its magnetic field. These are affected by many parameters, and some of them are not obvious at all. The best example is the magnet shape, different [...]
Magnets technical information The determining of magnetic properties is often not given its proper place along the development path of a product. These basic but important considerations are commonly considered as features which will adapt themselves into the required format at a later date. This may be true for applications using low coercive materials such [...]
Brief Introduction to Neodymium Magnet Materials The third generation of rare earth permanent magnet, Neodymium Iron Boron (Neodymium magnets), is the most powerful permanent magnet in modern magnets. Neodymium Magnet Materials The highest Remanence (Br) of Neodymium magnet1 is 3.8 times that of ferrite magnet, 1.1 times of that of Aluminum Nickel cobalt [...]
