B-H Curve for Permanent Magnets What is a B-H curve first of all? B is the nomenclature for magnetic flux density (induction) and H is magnetic field strength; a B-H curve plots out the relationship between them for a particular ferromagnetic material. The changes in magnetic flux density is dependent on the magnetic field strength. [...]
Various shapes Magnets Magnetization Orientation Neodymium, ceramic, samarium cobalt magnets can be custom-made in various shapes, sizes and magnetization orientations or directions. In this article, we list out and illustrate some of the available options for magnetization orientation which is defined during pressing process and prior to magnetization. Of course, engineers can always request otherwise [...]
Large Undulator Neodymium Permanent Magnets China MPCO MAGNETICS has some customers, who request permanent magnets for undulator, like N50M neodymium arc magnets in large sizes, with cutted sides, Nickel coating, working temperature 80 ℃. Customers usually send us drawings with enough information. A few of them require spread of magnetization less than 0.5%. As for [...]
Magnetic Magnetization Patterns Isotropic magnets, such as Bonded Nd-Fe-B, are unoriented and have no preferred direction; therefore it is possible to magnetize them in any direction. Almost all other materials are anisotropic and have a preferred direction of magnetization. They will exhibit the best magnetic properties when magnetized in the direction of the grain. Higher [...]
Magnetizing or Magnetization In magnetizing the magnetic domains inside of a magnet are aligned with the magnetizing field. If the magnetizing field strength is high enough, all the domains will be aligned and the magnet is said to be magnetized to saturation. Magnetizing to saturation is usually recommended as only then are the magnetic properties [...]
Orientated Magnets Direction, Direction of orientation For ‘Orientated Magnets Direction / direction of orientation’ it is understood the position of the magnetic cristals in a specific direction. In the correct direction, the magnet reaches its magnetic values and thus, should be magnetized in this direction. The direction of orientation is achieved by exposing the magnetic [...]
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 [...]
