Computational Design of Rare-Earth Reduced Permanent Magnets
Engineering, 2020 Multiscale simulation is a key research tool in the quest for new permanent magnets. Starting with first principles methods, a sequence of simulation methods can be applied to calculate the maximum possible coercive field and expected energy density ...

Manganese-based Permanent Magnets
Metals, 2015 There is a significant gap between the energy product, BH, where B is the magnetic flux density and H is the magnetic field strength, of both the traditional ferrite and AlNiCo permanent magnets of less than 10 MGOe and that of the rare earth magnets of ...

Permanent magnet based dipole magnets for next generation light sources
Physical Review Accelerators and Beams, 2017 We have developed permanent magnet based dipole magnets for the next generation light sources. Permanent magnets are advantageous over electromagnets in that they consume less power, are physically more compact, and there is a less risk of power supply ...

Stellarators with Permanent Magnets [PDF]
Physical Review Letters, 2020 It is shown that the magnetic-field coils of a stellarator can, at least in principle, be substantially simplified by the use of permanent magnets. Such magnets cannot create toroidal magnetic flux but they can be used to shape the plasma and thus to create poloidal flux and rotational transform, thereby easing the requirements on the magnetic-field ...

Study on the magnetic viscosity of multi-step magnetized heterogeneous alloys
Journal of Materials Research and Technology, 2023 The multi-step magnetization behavior caused by a variety of microstructures is common in magnetic materials. The study of the effect of heterogeneous structure magnetization behavior on magnetic viscosity provides extensive guidance for the long-term ...

Characterization of Permanent Magnet Magnetization [PDF]
IEEE Transactions on Magnetics, 2017 The performances of electrical machines highly depend on the behavior of materials, such as steel, copper, and permanent magnet. This paper focuses on permanent magnets whose magnetization must be precisely known. Thus a non-destructive approach which includes a combination of experiments and inverse problem, using the magnetostatic moment method, is ...

Optimized design of permanent magnet for disk permanent magnet governor
Scientific Reports, 2023 AbstractTo research the magnetic field and mechanical characteristics of the permanent magnet governor, the static magnetic field of the sector permanent magnet is analyzed by the molecular current method in the permanent magnet governor. The magnetic flux distribution is acquired at any spatial position.
