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, [...]
How to distinguish the north and south poles of magnet? Magnets are widely used in various industries, because of magnetic adsorption and magnetic induction, many electronic products, hardware, machinery and other industries! So before many customers use magnets, there is a doubt, how to distinguish the north and south poles of the magnet, because the [...]
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 [...]
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 [...]
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 [...]
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 [...]
What are the difficulties when cutting ferrite magnets? A ferrite magnet is a metal oxide having ferromagnetism. In terms of electrical characteristics, ferrite magnets have much higher electrical resistivity than metal and alloy magnetic materials, and also have higher dielectric functions. The magnetic function of the ferrite magnet also exhibits a high magnetic permeability at [...]
How to Judge Neodymium Iron Boron Magnet Quality Neodymium Iron Boron Magnet Quality - In the past 30 years, with the extensive development of magnet products, NdFeB magnets have been widely used in various industries, especially in magnetic levitation, electronic digital products and other industries. In the past 30 years, there have been many different brands. [...]
N35 And N52 Magnet In the marketing process, some customers do not understand the meaning of the N35, N52 magnet, then what is the matter? In the market, we talk about the neodymium iron boron magnetism. Actually, there are many material grades in the strong magnetism. The magnetic energy product in each grade is different. [...]
Magnet Can Cure Eye Tremor Recently, an article published in Ophthalmology magazine introduced a case of magnetic implants for the treatment of nystagmus, the first report of the use of implants to control eye movements. Researchers at the University of London and Oxford have implanted a magnetic device into the eye and successfully cured a [...]
