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 [...]
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 [...]
Notice About Powerful Magnets Storing, store strong magnets What should you pay attention to when powerful magnets storing? When storing magnets, especially powerful magnets, there are many things to note: 1. It is necessary to keep the ventilation and drying of the storage environment as much as possible. Otherwise, the humid environment is very easy [...]
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 [...]
Magnetic materials are expected to be used for cancer treatment A special type of magnetic material that achieves a specific self-regulating heating effect and is expected to provide a new way of thinking for the treatment of cancer by hyperthermia. The researchers said, "This intense self-regulating thermal effect is unmatched by other materials, and it [...]
Three main causes of permanent magnet demagnetization during motor use Frequently, motor customers will encounter the problem of permanent magnet demagnetization. What is going on? What could be caused by? Today, the magnet manufacturer MPCO MAGNETICS tells everyone about the three main causes of permanent magnet demagnetization in the actual use of the motor. First, [...]
Countersunk NdFeB Magnet Production and Processing With the continuous advancement of industrial civilization, the current NdFeB magnets are no longer the same as before, and the proportion of magnetic rings and countersinks is also increasing. In other words, this process is becoming more and more popular. universal. However, many customers have found our MPCO magnet [...]
Rare earth permanent magnet costs rise, motor companies' profits plummet, The motor industry said that more than 200 companies will be eliminated more than half "New energy passenger cars have very high requirements on motor quality. A large number of independent motor enterprises will be eliminated. By then, the killing of China's new energy automobile [...]
Offshore Wind Has a Looming Rare Earth Metals Problem Offshore wind power seems to be on the cusp of taking off in the U.S. That’s great news for the climate, but every technology has a cost. As a new study points out, a surge in offshore wind could also mean a surge in our appetite [...]
