Causes and avoidance of rust spots on NdFeB magnets After a period of time, the neodymium iron boron strong magnet will appear white or other color spots on the surface, and it will become rust spots when it develops slowly. Under normal circumstances, the plating of the electromagnet is not easy to appear rust spots, [...]
Strong Magnet Performance Curve, Demagnetization of Permanent Magnets, Demagnetization curves for a Nd-Fe-B The value of the reverse magnetic field strength required to reduce the magnetic induction to zero when the magnet is magnetized by reverse magnetization in the reverse magnetization is called the magnetic coercive force (Hcb). However, the magnetization of the magnet is [...]
NdFeB Magnet Price Trend After the effective control of rare earth NdFeB magnets in the past two years, the price tends to be stable, the rational development and utilization of rare earth minerals are effectively controlled, and the production of rare earth magnet raw materials is gradually stable. The raw material prices are stable throughout [...]
What to pay attention to when using a powerful magnet The application of magnets in everyday life is more common. There are a variety of magnets on the market, such as strong neodymium iron boron magnets, permanent magnet ferrites, and aluminium nickel cobalt magnets. Now, the performance of iron-boron magnets is still very good. In [...]
New Trends of Rare Earth Permanent Magnet Industry in China Rare Earth Permanent Magnet Industry - Rare earth permanent magnet materials represented by samarium cobalt (Sm-Co) and neodymium iron boron (NdFeB) are the most permanent magnet magnetic materials in the world, and are widely used in many national economies such as information and communication, electronic [...]
Rare Earth: Important Strategic Resources Foreword: Xi Jinping visited Jiangxi Jinli Permanent Magnet on May 20, 2019 to understand the development of the company and the development of the rare earth industry. It is then proposed that rare earth is an important strategic resource and a non-renewable resource. It is necessary to increase scientific and [...]
Magnet Demagnetization Method Strong magnets can be magnetized and demagnetized, because the magnet itself is or will be magnetic, so we can make a certain method to demagnetize according to the use of strong magnets. Magnet Demagnetization Method Vibration demagnetization method: The operation of this method is very simple, that is, the powerful [...]
How to Separate Strong Magnets? Strong magnets are magnetic after magnetization. In the next process, multiple magnets may need to be separated. Because the magnets of strong magnets are very strong, it is more difficult to separate the magnets. So how do we separate the powerful magnets operating? How to Separate Strong Magnets [...]
Ferrite Magnets Overview Ceramic magnets are permanent magnets made up of a composite of iron oxide and barium/strontium carbonate. Through pressing and sintering ceramic magnets are made. These magnets are also made in different grades. They are widely used magnets with good magnetic strength and resistance to demagnetization. The color of ceramic magnet is charcoal [...]
Modeling Eddy Current Losses in Permanent Magnet Motor Let’s begin with our model geometry. In this example, we have a 3D model of an 18-pole PM motor. To reduce computational efforts and capture the full 3D behavior of the motor, we use sector symmetry and axial mirror symmetry. You can see an animation of the [...]
Determine Strong Magnet Quality NdFeB magnets are popular word products in the market. At present, the demand in China's market is getting bigger and bigger, and the bidding is getting bigger and bigger. Many magnet manufacturers have better competitive advantages in the market. Will reduce the cost by using inferior raw materials. Therefore, when buying [...]
Take you to know how magnets are produced Due to the wide variety of magnets, the usual manufacturing method is to sinter rare earth permanent magnets. For raw materials such as samarium cobalt and neodymium iron boron, sintering is carried out under vacuum or a protective atmosphere, post-treatment and mechanical processing, and the processing components [...]
