The role of magnet powder in NdFeB Magnetic powder is an abbreviation for magnetic powder, and is an aggregate composed of a large amount of NdFeB basic material particles and interparticle voids. The powder body is a substance between a solid and a colloid. Solids below 0.1 μm are referred to as colloids, while solids [...]
What is Speaker Magnet The neodymium speaker magnet produces a magnetic field, and the speaker’s voice coil motor is placed in the magnetic field. When the voice coil passes through the audio current, the current will be acted by the magnetic field, which causes the voice coil to vibrate, and drives the paper basin that [...]
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 [...]
MPCO's Magnetic Rails (MPMRAIL series) are engineered for simple installation into new or existing belted conveyor applications. MPCO Magnetic Rails are used to hold and position ferrous parts. They are ideal for use in can handling as well as other applications which require a high reaching magnetic field. MPCO Magnetic Rails are often used in [...]
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 [...]
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 [...]
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 [...]
Rare earth permanent magnet application in information technology It is well known that magnetic materials such as permanent magnets (also called hard magnet), soft magnetic and gyromagnetic materials in magnetic materials are important functional materials for the information industry. They play a very important role in traditional information departments including telecommunications, telephone, printing, publishing, news, [...]
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 [...]
