Why current-carrying magnetic flux tubes gobble up plasma and become thin as a result [PDF]

open access: yes, 2003
It is shown that if a current-carrying magnetic flux tube is bulged at its axial midpoint z=0 and constricted at its axial endpoints z=+h,-h, then plasma will be accelerated from z=+h,-h towards z=0 resulting in a situation similar to two water jets ...

Residual Flux Density Measurement Method of Single-Phase Transformer Core Based on Time Constant

open access: yesIEEE Access, 2020
Residual flux density in the single-phase transformer core can dramatically increase inrush current when the transformer is energized. To reduce inrush current, it is necessary to study residual flux density measurement.

Enhancement of critical current density and vortex activation energy in proton-irradiated Co-doped BaFe2As2

open access: yes, 2012
The effect of proton irradiation in Ba(Fe0.93Co0.07)2As2 single crystals is reported. We analyze temperature dependence of current density and normalized flux relaxation rate in the framework of collective creep model.

Iron loss in permanent-magnet brushless AC machines under maximum torque per ampere and flux weakening control [PDF]

open access: yes, 2002
The airgap flux density distribution, flux density loci in the stator core, and the associated iron loss in two topologies of brushless AC motor, having a surface-mounted magnet rotor and an interior-mounted magnet rotor, respectively, are investigated ...

Optimization of flux-surface density variation in stellarator plasmas with respect to the transport of collisional impurities [PDF]

open access: yes, 2019
Avoiding impurity accumulation is a requirement for steady-state stellarator operation. The accumulation of impurities can be heavily affected by variations in their density on the flux-surface.

Study on the residual flux density measurement method for power transformer cores based on magnetising inductance

open access: yesIET Electric Power Applications, 2022
When a power transformer is reconnected to a power grid, if the residual flux in its iron core is large, significant inrush current may be generated and result in closing failure.

Magnetic flux density distribution in axial flux machine cores [PDF]

open access: yes, 2005
[Abstract]: A three-dimensional analytical model is presented to evaluate the magnetic flux density distribution in the core of an axial flux machine. The model predicts significantly higher flux density near the outer radius of the core than that at the

Feasibility and Preliminary Efficacy of Integrative Neuromuscular Training for Childhood Cancer Survivors: A Pilot Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of childhood acute lymphoblastic leukemia (ALL) often exhibit early deficits in muscle and movement competence, which can compromise long‐term health. Integrative neuromuscular training (INT), a multifaceted approach combining fundamental movement activities with strength exercises, may help address these deficits during ...
