Operating Point, Load Line and Permeability Pc of Permanent Magnet The permanent magnet works in the open circuit state. Since the magnet in the open circuit state is under the action of the demagnetization field, the magnetic induction intensity of the permanent magnet in the working state is not at the Br point in the [...]
Anisotropy of Permanent Magnet Shape and Demagnetization Field and Demagnetization Factor Make the permanent magnet into a certain shape. Take the block magnet in the following figure as an example. If you measure the magnetization curve in the open circuit state along the x, y, and z directions of the magnet, you can find that [...]
Safety Essentials for Parents: Small Magnet Safety Reminder Small magnet safety reminder Parents and caregivers are advised to exercise caution when exposing children to products with small magnets. These can be life-threatening if swallowed accidentally. Small, powerful magnets are also increasingly used in novelty items. Younger kids may mistake these colorful magnets for candy and [...]
The Origin of Magnetism and Negative Temperature Characteristic in Finite Level Magnetic System The magnetism of matter is a deceptively simple problem that is actually quite subtle. In history, magnetism was discovered by humans very early. But it is strange that such "simple" magnetism cannot be described by classical physics, which seems so powerful! Specifically, [...]
Can't get enough of hands-on electromagnetic experiments? We have some more ideas for you to try: What is the magnetic power of a single coil wrapped around a nail? Of 10 turns of wire? Of 100 turns? Experiment with different numbers of turns and see what happens. One way to measure and compare a magnet's [...]
MAGNETIC TECHNICAL CHARACTERISTICS PRODUCTS Deviations from shapes and positions, tolerances Magnetics materials Magnetic Force Direction of orientation Direction of magnetization Shapes of magnets Terminology and definitions Neodymium Qualities HSMAG works daily with the commitment and responsibility to ensure a product with a high level of quality. Permanent magnets are used in almost all industrial sectors. [...]
MULTI-POLE MAGNETIC CIRCUIT COMPARISONS Permanent magnets can be magnetized with two or more (4, 6, 8, etc.) poles, using permanent or pulse magnetic flux. Pulse magnetization allows achievement of larger magnetic fields necessary for Nd-Fe-B or Sm-Co magnets. Multi-pole magnetization requires special magnetization heads with preformed windings which allow achievement of required distribution of magnetic [...]
Undulator Magnets Undulator is one of the key equipment of the third-generation synchrotron light source and free electron laser device. Permanent magnet vacuum undulator occupies a fairly large proportion in numerous permanent magnet undulators. Undulator magnet is regarded as the heart of vacuum undulator. Its comprehensive magnetic characteristics have significant influence on the peak value, [...]
Understanding Magnetic Permeability Magnetic Permeability is a value that expresses how a magnetic material responds to an applied magnetic field. If a material's internal dipoles become easily oriented to an applied magnetic field, that material is regarded as being a high-permeability material. If the material's internal dipoles do not become easily oriented to an applied [...]
