Coupling currents in Rutherford cables under time varying conditions [PDF]

open access: yes, 1992
A network model is presented to simulate fully transposed Rutherford cables under time varying conditions. The intrinsic properties of the cable and the external applied conditions can be changed spatially.

Mechanism Analysis of Eddy-Current Effects on Switching Power Amplifier of a Nonlaminated Magnetic Bearing

open access: yesIEEE Access, 2020
For thrust magnetic bearings (TMB), the stators and thrust disks are commonly made of nonlaminated material. Therefore, eddy currents are inevitable in solid ferromagnetic cores.

СТРУМИ ТА ЕЛЕКТРОМАГНІТНІ ЗУСИЛЛЯ В СИСТЕМАХ МАГНІТНО-ІМПУЛЬСНОЇ ОБРОБКИ З ФЕРОМАГНІТНОЮ ПЛАТФОРМОЮ

open access: yesПраці Інституту електродинаміки Національної академії наук України, 2022
The action of high-density pulsed currents (109 A/m2) leads to the appearance of the electro-plastic effect in metal products. It is proposed to use magnetic pulse treatment of nonmagnetic plates by electromagnetic inductors with a U-shaped magnetic ...

Damage detection of cracks in carbon fibre reinforced composites by pulsed eddy-current testing

open access: yesMATEC Web of Conferences, 2018
Non-destructive evaluation techniques that are based on electromagnetic methods are commonly used for inspection of metallic and carbon fibre reinforced plastics parts. Some of these inspection methods are based on eddycurrents which are generated by the

Methodology for Eddy Current Losses Calculation in Linear Variable Differential Transformers (LVDTs)

open access: yesSensors, 2023
Linear variable differential transformer (LVDT) is a commonly used linear displacement sensor because of its good measurement characteristics. When using laminated ferromagnetic cores in LVDTs, it is very important to take eddy currents into the account ...

An approach to explore the eddy currents of the new type divertor for EAST device using ANSYS code [PDF]

open access: yes, 2016
An effective method for eddy current calculation has been developed for EAST’s new divertor by using ANSYS. A 3D model of a double null divertor for the EAST device was built to evaluate eddy currents and electromagnetic (EM) forces on these components ...

Simulated design strategies for SPECT collimators to reduce the eddy currents induced by MRI gradient fields [PDF]

open access: yes, 2015
Combining single photon emission computed tomography (SPECT) with magnetic resonance imaging (MRI) requires the insertion of highly conductive SPECT collimators inside the MRI scanner, resulting in an induced eddy current disturbing the combined system ...

Numerical Homogenization for the Calculation of Eddy Current Losses in a Laminated Open Core

open access: yesIEEE Access
Eddy currents are decoupled into narrow eddy currents, induced by the magnetic flux tangential to the laminations, and planar eddy currents, induced by the magnetic flux perpendicular to the laminations.
