1.A rock, piece of metal, or other solid that has the property of attracting iron or steel. A lodestone is a natural magnet, but most magnets today are made by inducing magnetism in a material such as steel or a metal alloy. Magnets have two magnetic poles, called north and south. ...
Influence of the amount of permanent magnet material in fractional-slot permanent magnet synchronous machines The efficiency of permanent-magnet (PM) synchronous machines with outer rotor and concentrated windings is investigated as a function of the mass of magnets used, keeping the power... 查看...
D. atom 答案:atom Crystallinestructureis a description of the ordered arrangement of atoms, ions or molecules in acrystallinematerial. We often use ___to illustrate the 3D structure, which is an array of \small boxes\ infinitely repeating in three spatial directions. A. unit cell B. crystal...
At this time, a roll having 0.07-1.5mum average surface roughness Ra along the center line is used as the cooling roll. The roughness Ra of the cooled alloy is regulated to 0.05-1.5mum and a permanent magnet material whose roughness Ra is below that of the cooling roll is produced. 展开...

[Also in Division C7] Magnetic material consists of magnetic particles (diameter <30) coated with metal. The magnetic particles consist of an alloy of the system M-R within the region of homogeneity which includes M-R and in which all alloys have the same hexagonal crystal structure as M 5...
The property of the electrode material can also affect the efficiency of the electrolysis. Ferromagnetic materials give greater higher efficiency than paramagnetic materials or diamagnetic materials. The effectiveness of hydrogen production is significantly enhanced in a shorter inter-electrode under an ...
1. A method of making a permanent magnet consisting of at least one rare earth element, at least one transition metal and boron as the main ingredients characterised by casting a raw material including the main ingredients to produce a cast body having a columnar macrostructure such that the ca...
6. The magnetic hysteresis of permanent magnets is mainly characterized by the factors of high saturation magnetization, high remanent magnetization, large coercivity, and good squareness. Among them, only the saturation magnetization is an intrinsic property of the material; the others are related to...
