The First Magnetic Fields [PDF]

open access: yesSpace Science Reviews, 2011
We review current ideas on the origin of galactic and extragalactic magnetic fields. We begin by summarizing observations of magnetic fields at cosmological redshifts and on cosmological scales. These observations translate into constraints on the strength and scale magnetic fields must have during the early stages of galaxy formation in order to seed ...

Electrochemistry in Magnetic Fields

open access: yesAngewandte Chemie International Edition, 2022
AbstractDeveloping new strategies to advance the fundamental understanding of electrochemistry is crucial to mitigating multiple contemporary technological challenges. In this regard, magnetoelectrochemistry offers many strategic advantages in controlling and understanding electrochemical reactions that might be tricky to regulate in conventional ...

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.

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.

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 ...

Solar magnetic fields [PDF]

open access: yesPhysics of the Earth and Planetary Interiors, 2011
This review provides an introduction to the generation and evolution of the Sun's magnetic field, summarising both observational evidence and theoretical models. The eleven year solar cycle, which is well known from a variety of observed quantities, strongly supports the idea of a large-scale solar dynamo.
