Magnetically confined mountains on accreting neutron stars with multipole magnetic fields [PDF]

open access: yes, 2022
Magnetically confined mountains on accreting neutron stars are candidates for producing continuous gravitational waves. We formulate a magnetically confined mountain on a neutron star with strong multipole magnetic fields and obtain some sequences of numerical solutions.

Superconducting Magnet System Concept with a Mechanical Energy Transfer in the Magnetic Field [PDF]

open access: yes, 2022
There is an interest to design superconducting magnet systems working in a persistent current mode. These systems continuously generate magnetic field with disconnected power source working like permanent magnet devices. In this paper proposed a magnet system concept based on the direct mechanical energy transfer in the magnetic field.

Characterization of Permanent Magnet Magnetization [PDF]

open access: yesIEEE 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 ...

An optimized magnet for magnetic refrigeration [PDF]

open access: yesJournal of Magnetism and Magnetic Materials, 2010
A magnet designed for use in a magnetic refrigeration device is presented. The magnet is designed by applying two general schemes for improving a magnet design to a concentric Halbach cylinder magnet design and dimensioning and segmenting this design in an optimum way followed by the construction of the actual magnet.
