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

On the Modernisation of Weber’s Electrodynamics
Magnetism, 2023 This work is an attempt to modernise Weber’s electrodynamics to make it compatible with the high-velocity regime, and with the existence of a limiting velocity, c.

Stacking-Dependent Magnetism in Bilayer CrI3. [PDF]
Nano letters (Print), 2018 We report the connection between the stacking order and magnetic properties of bilayer CrI3 using first-principles calculations. We show that the stacking order defines the magnetic ground state.

An optimized magnet for magnetic refrigeration [PDF]
Journal 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.

Effect of Laminated Core Body Size on Motor Magnetic Properties
Magnetism, 2023 The magnetic characteristics of electromagnetic steel sheets used for motors are evaluated under ideal sinusoidal excitation. However, in actual equipment driving, excitation by pulse-width modulation (PWM) waves is the mainstream method.

Direct visualization of magnetic domains and moiré magnetism in twisted 2D magnets
Science, 2021 Description Imaging twisty magnets Twisting monolayers of graphene with respect to each other has led to a number of unusual correlated states. This approach has inspired researchers to try their hand at twisting two-dimensional (2D) magnets, but such ...
