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 [...]
Magnet used in Medicine Today we are talking about magnets. With the development of the times, magnets have gradually entered every corner of our lives. But do you know? Magnets not only have good value in industry, but also magical effects on magnets in medical applications. Let's take a look at them together! Analgesia: Magnetic [...]
The Future Development Trend of NdFeB Magnets 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 [...]
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. [...]
Precautions for Custom Powerful Magnets For those old drivers who have used magnets for many years, the company's engineering has a basic understanding of the characteristics of powerful magnets and the size of the products required magnet, but for some companies that have not used magnets, they don’t understand the powerful magnets. What issues should [...]
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 [...]
Safty Advice for Using Magnets Please observe the followings to avoid injury or magnetic properties deterioration: 1 When you use the magnets, you must keep the wroking environment clean; otherwise the magnets will absorb iron dust or other particles and affect its use. 2 The magnets should be fixed when you magnetize it. The magnetic [...]
Permanent magnet materials, also known as hard magnetic materials, are characterized by high anisotropy field, high coercivity, large hysteresis loop area, large magnetization field required for magnetization to saturation, and strong long-term retention after removal of external magnetic fields. Magnetic. In practice, the permanent magnet material operates in the second quadrant demagnetization portion of the [...]
Chemically Controlled Magnetic Material Magnets are common in physics classes at school, but almost no chemistry classes are involved; researchers have successfully used chemical methods to control the magnetic properties of ferromagnetic substrates. Physical methods may affect the direction of the magnetic field. The chemical method in this example finely controls the selected ferromagnetic material [...]
