Sintered NdFeB magnets are the most powerful commercialized permanent magnets available today, with maximum energy product ranging from 26 MGOe to 52 MGOe. Nd-Fe-B is the third generation of permanent magnet developed in the 1980s. It has a combination of very high remanence and coercivity, and comes with a wide range of grades, sizes and shapes. With its excellent magnetic characteristics, abundant raw material and relatively low prices, Nd-Fe-B offers more flexibility in designing of new or replace the traditional magnet materials such as ceramic, Alnico and Sm-Co to achieve high efficiency, low cost and more compact devices. Advantages *Extreme strong Br Resident induction. *Excellent demagnetization resistance capability. *Good Price relative to its high magnetic properties. Magnetic characteristics of sintered NdFeb Note:The above mentioned data is given at room temperature. The above-mentioned maximum working temperature of magnet is changeable due to the ratio length and diameter,surface coating and environmental factors. FAQ 1.

Fast Delivery: when you choose the item and decide your design, we can produce it as fast as possible. 5. If you would like to make an enquiry, how can you contact us? 6. The way of identify the pole of magnet: The easiest way is to make a dot on the North or South or both Poles. If you need, we can make the dot as your requirement 7.Is one pole stronger than the other? No, both poles are equally strong 8.Which is the strongest type of magnet? Neodymium (more precisely Neodymium-Iron-Boron) magnets are the strongest permanent magnets in the world. 9.Can you supply BH Curves, or Demagnetization Curves for your magnets? Yes, we've offered Demagnetization Curves for our most common Neodymium magnet grades right here. 10.Will my neodymium magnets lose strength over time? Very little. Neodymium magnets are the strongest and most permanent magnets known to man. If they are not overheated or physically damaged, neodymium magnets will lose less than 1% of their strength over 10 years - not enough for you to notice unless you have very sensitive measuring equipment. They won't even lose their strength if they are held in repelling or attracting positions with other magnets over long periods of time. carton
Neodymium Magnets China Manufacturer Custom Neodymium Arc Shaped Magnets Arc magnets are mainly used in permanent magnet DC motors. Unlike electromagnetic motors that generate magnetic potential sources through excitation coils, PM motors use permanent magnet materials to generate constant magnetic potential sources. Instead of electric excitation, permanent arc magnets have many advantages, which can make the motor simple in structure, convenient in maintenance, light in weight, small in size, reliable in use, low in copper consumption, and low in energy consumption.

Custom Neodymium Magnet Shapes Rare Earth Magnets China Manufacturer In the design of high-speed permanent magnet motor, the materials currently used usually have high coercivity. This is mainly due to the relatively low temperature coefficient of materials with high coercivity, which is more conducive to ensuring high-speed permanent magnets. The temperature of the motor rotor is relatively more stable. At the same time, materials with high coercivity have higher temperature adaptability and are currently used in a wide range of applications with higher temperatures. In addition, materials with higher coercivity usually have relatively higher compression resistance and anti-interference strength, and the centrifugal force that can withstand is relatively higher.

Custom Neodymium Magnets Components Halbach Array Ring Neodymium Magnetic The Halbach Array is entirely composed of rare earth permanent magnet materials. By arranging the permanent magnets with different magnetization directions according to a certain rule, the magnetic field lines can be concentrated on one side of the magnet, and the magnetic field lines can be weakened on the other side, thereby obtaining an ideal unilateral magnetic field. This is of great significance in engineering. With excellent magnetic field distribution characteristics, Halbach Arrays are widely used in industrial fields such as nuclear magnetic resonance, magnetic levitation, and permanent magnet motors.
