Magnetic core model

open access: yesIET Science, Measurement & Technology, 2007
The paper presents a nonlinear electric circuit to describe the behaviour of magnetic cores in low-frequency applications. A method of hysteresis modelling is proposed, which is able to reproduce minor loops and remanent flux. Classic eddy-current losses and anomalous losses are represented by a linear resistor and a non linear resistor, respectively ...

Distortion of Magnetic Fields in a Starless Core: Near-Infrared Polarimetry of FeSt 1-457 [PDF]

open access: yes, 2017
Magnetic fields are believed to play an important role in controlling the stability and contraction of dense condensations of gas and dust leading to the formation of stars and planetary systems.

The nonisothermal stage of magnetic star formation. II. Results

open access: yes, 2010
In a previous paper we formulated the problem of the formation and evolution of fragments (or cores) in magnetically-supported, self-gravitating molecular clouds in axisymmetric geometry, accounting for the effects of ambipolar diffusion and Ohmic ...

Optimal Design and Development of Magnetic Field Detection Sensor for AC Power Cable

open access: yesSensors
The state detection of power cables is very important to ensure the reliability of the power supply. Traditional sensors are mostly based on electric field detection. The operation is complex, and its efficiency needs to be improved. This paper optimizes

Analytical Method for Compensation Choke Geometry Optimization to Minimize Losses

open access: yesIEEE Access, 2022
The article presents an analytical method for optimizing the geometry of the magnetic core of a three-phase compensation choke. The method describes the process of identification the fringing magnetic fields and the corresponding magnetic reluctances of ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

SCUBA polarisation observations of the magnetic fields in the prestellar cores L1498 and L1517B [PDF]

open access: yes, 2006
We have mapped linearly polarized dust emission from the prestellar cores L1498 and L1517B with the James Clerk Maxwell Telescope (JCMT) using the Submillimetre Common User Bolometer Array (SCUBA) and its polarimeter SCUBAPOL at a wavelength of 850um. We
