Electrical effects in winding of large electrical ac machines application to advanced large size DFIM

To meet the electrical grid's demand on pump power variation, GE Renewable Energy develops since 10 years variable speed machines (also called Doubly Fed Induction Generators or DFIG). Within turbogenerators, the phenomenon of circulating currents in Roebe ...

Lorentz Force from a Current-Carrying Wire on a Charge in Motion under the Assumption of Neutrality in the Symmetrical Frame of Reference

Marcos Rubinstein, Antonio Sunjerga

It is commonly assumed that a wire conducting an electric current is neutral in the laboratory frame of reference (the rest frame of the lattice of positive ions). Some authors consider that the wire is neutral only in a symmetrical frame of reference, in ...

Direct enhancement of nitrogen-15 targets at high-field by fast ADAPT-SABRE

Gabriele Stevanato

Signal Amplification by Reversible Exchange (SABRE) is an attractive nuclear spin hyperpolarization technique capable of huge sensitivity enhancement in nuclear magnetic resonance (NMR) detection. The resonance condition of SABRE hyperpolarization depends ...

Angular-dependent magnetization dynamics of kagome artificial spin ice incorporating topological defects

Dirk Grundler, Vinayak Shantaram Bhat

We report angular-dependent spin-wave spectroscopy on kagome artificial spin ice made of large arrays of interconnected Ni80Fe20 nanobars. Spectra taken in saturated and disordered states exhibit a series of resonances with characteristic in-plane angular ...

Contained density currents with high volume of release

Mário Jorge Rodrigues Pereira Da Franca, Quentin Theiler

Contained density currents with high volume of release reflect against the boundaries of the reception environment commonly leading to oscillatory flow. These flows exist in sediment clarifiers, compromising their operations, and deposited signatures of co ...

A mathematical and numerical framework for ultrasonically-induced Lorentz force electrical impedance tomography

Pierre Robert Maurice Millien

We provide a mathematical analysis and a numerical framework for Lorentz force electrical conductivity imaging. Ultrasonic vibration of a tissue in the presence of a static magnetic field induces an electrical current by the Lorentz force. This current can ...

Electrical Neuroimaging with Irrotational Sources

This paper discusses theoretical aspects of the modeling of the sources of the EEG (i.e., the bioelectromagnetic inverse problem or source localization problem). Using theHelmholtz decomposition (HD) of the current density vector (CDV) of the primary curre ...

AC Magnetoelectrical Susceptibility Study of Multiferroics

Abhisek Datta

Multiferroics are materials in which ferroelectric and magnetic e.g., ferromagnetic or antiferromagnetic orders co-exist. Some of these show the magnetoelectric effect which is the coupling between electric and magnetic degrees of freedom leading to induct ...

Mobility Measurement in Nanowires Based on Magnetic Field-Induced Current Splitting Method in H-Shape Devices

Jean-Michel Sallese, Didier Bouvet, Farzan Jazaeri, Lucian Barbut

This work investigates a new method to measure mobility in nanowires. Based on a simple analytical approach and numerical simulations, we bring evidence that the traditional technique of Hall voltage measurement in low dimensional structures such as nanowi ...

Pre-sheath density drop induced by ion-neutral friction along plasma blobs and implications for blob velocities

Ambrogio Fasoli, Ivo Furno, Christian Gabriel Theiler, Joaquim Loizu Cisquella

The pre-sheath density drop along the magnetic field in field-aligned, radially propagating plasma blobs is investigated in the TORPEX toroidal experiment [Fasoli et al., Plasma Phys. Controlled Fusion 52, 124020 (2010)]. Using Langmuir probes precisely al ...
