Magnetic Fields of F-Type Stars [PDF]

open access: yes, 2022
Magnetic fields are an observable feature of many stars, with warm, F-type stars of interest in searching for the transition from the fossil fields in hot stars to dynamos in cool stars driven by convection zones.

On the topology of global coronal magnetic fields [PDF]

open access: yes, 2014
This thesis considers the magnetic topology of the global solar corona. To understand the magnetic topology we use the magnetic skeleton which provides us with a robust description of the magnetic field.

Cosmology with inhomogeneous magnetic fields [PDF]

open access: yes, 2007
We review spacetime dynamics in the presence of large-scale electromagnetic fields and then consider the effects of the magnetic component on perturbations to a spatially homogeneous and isotropic universe.

On the vertigo due to static magnetic fields. [PDF]

open access: yes, 2013
Vertigo is sometimes experienced in and around MRI scanners. Mechanisms involving stimulation of the vestibular system by movement in magnetic fields or magnetic field spatial gradients have been proposed.

PRIMORDIAL MAGNETIC FIELDS [PDF]

open access: yesInternational Journal of Modern Physics D, 1998
The explanation of the observed galactic magnetic fields may require the existence of a primordial magnetic field. Such a field may arise during the early cosmological phase transitions, or because of other particle physics related phenomena in the very early universe reviewed here.

The investigation of quasi-separatrix layers in solar magnetic fields [PDF]

open access: yes, 2011
The structure of the magnetic field is often an important factor in many energetic processes in the solar corona. To determine the topology of the magnetic field features such as null points, separatrix surfaces, and separators must be found.

Feasibility of Parylene Coating for Planar Electroporation Copper Electrodes

open access: yesMedžiagotyra, 2017
This paper is focused on the feasibility study of parylene as a biocompatible coating for planar electroporation microelectrodes. The planar parallel and the circular interdigitated electrodes are applied in the analysis.

A mathematical model and experimental procedure to analyze the cognitive effects of audio frequency magnetic fields

open access: yesFrontiers in Human Neuroscience, 2023
Audio frequency magnetic fields (20 Hz−20 kHz) are magnetic fields in extremely low frequency-very low frequency (ELF-VLF) bands that are present near audio equipment and acoustic transducers.

Zero Magnetic Field Type Magnetic Field Sensor

open access: yesIEEJ Transactions on Electronics, Information and Systems, 1990
AbstractThis paper presents a new magnetic field sensor named the zero magnetic field type, on the basis of its principle of operation, which is as follows: when the magnetic field level in the core used as a sensor is shifted by an unknown field to be detected, a controlled field is so superimposed in the opposite direction to the unknown field that ...
