Strong Magnet Magnetization Orientation How do you differ from the north pole of a strong magnet without being marked? Obviously, it is impossible to distinguish between eyes alone. The compass can be used to approximate the powerful magnet, and the pointer to the north pole of the earth points to the south pole of the [...]
High Temperature Resistance Magnets Not all magnets are suitable for use in really high-temperatures, while some grades excel. Many applications, particularly within the manufacturing and engineering industries require magnets to be able to maintain their performance at incredibly high temperatures. Here you will find a selection of ferrite, alnico, samarium cobalt and special high-temperature neodymium [...]
Three environmental factors affect function of high temperature resistant magnet Environment temperature. Since sintered NdFeB has a negative temperature coefficient (αBr<-0.13%/°C, αHcj<-0.6%/°C), the instantaneous maximum temperature and the continued maximum temperature of the operating environment will cause different degrees of demagnetization of the magnet itself. Contains reversible and irreversible, rehabilitative and non-recoverable. Environment humidity. NdFeB [...]
How to keep the magnet magnetism for a long time? Magnet, also known as permanent magnets, are objects that exist around the material and have their own magnetic fields. They are both natural and artificial. Artificial magnets are usually made of a metal alloy and have strong magnetism. Ferromagnetic refers to the magnetic state of [...]
How does the magnet manufacturer process magnet? Many people know magnets and learn to use them. They also know that magnets are widely used in society. So, how do magnet manufacturers handle magnets? Let me introduce some measures for magnets from MPCO magnet manufacturer. magnet manufacturer process magnet First, the magnet is [...]
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 [...]
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 [...]
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 [...]
