Magnetic Behavior of Sintered NdFeB Magnets on a Long-Term Timescale

open access: yesAdvances in Materials Science and Engineering, 2014
Stable polarization of permanent magnets over the lifetime of the application is an important aspect in electrical machine design. Specification of the long-term stability of magnet material is difficult, since knowledge of the phenomenon is incomplete ...

Anesthetic consideration for patients with micra leadless pacemaker

open access: yesAnnals of Cardiac Anaesthesia, 2020
MICRA, miniaturized leadless single chamber pacemaker, is inserted directly into the right ventricular myocardium via transcatheter approach. We present a case of a 66-year-old patient with a Micra pacemaker scheduled for kidney-pancreas transplant.

Magnetizing of permanent magnets using HTS bulk magnets

open access: yesCryogenics, 2011
A demagnetized Nd-Fe-B permanent magnet was scanned just above the magnetic pole containing the HTS bulk magnet, generating a magnetic field of 3.27 T. The magnet sample was subsequently found to be fully magnetized in the open space of the static magnetic fields.

Permanent Magnet minimization in PM-Assisted Synchronous Reluctance motors for wide speed range [PDF]

open access: yes, 2013
This paper presents a technique to modify the rotor lamination of a permanent-magnet-assisted synchronous reluctance motor, in order to reduce the magnet volume with no side effect on performance.

Magnetic field annihilators: invisible magnetization at the magnetic equator [PDF]

open access: yesGeophysical Journal International, 2003
SUMMARY Some distributions of magnetization give rise to magnetic fields that vanish everywhere above the surface, rendering these distributions of magnetization completely invisible. They are the annihilators of the magnetic inverse problem. Known examples are the infinite sheet with constant magnetization and the spherical shell of constant ...

Production of nanocrystalline soft magnetic powders with high Bs by an improved rapid-cooling water-atomization process

open access: yesAIP Advances, 2019
A powder of Fe83.3Si4B8P4Cu0.7 composition with D50 of 4.2 μm was prepared by the modified water atomization system named “HPWA/YK”. The obtained powder had a mostly amorphous single phase.

Analysis of anisotropic bonded NdFeB Halbach cylinders accounting for partial powder alignment [PDF]

open access: yes, 2000
An analytical technique is developed for predicting the performance of a bonded Halbach oriented anisotropic magnet, with due account of partial alignment of the NdFeB powder during injection molding.
