A Concept for 6D Motion Sensing with Magnetoelectric Sensors

Current Directions in Biomedical Engineering, 2022
Active magnetic motion sensing relies on a combination of magnetic sensors and actuators to indirectly sense a time-varying change in position and orientation.

Evolution of hydromagnetic turbulence from the electroweak phase transition

, 2017
We present new simulations of decaying hydromagnetic turbulence for a relativistic equation of state relevant to the early universe. We compare helical and nonhelical cases either with kinetically or magnetically dominated initial fields.

Simplified Model of the Solar Magnetic Field

The Astrophysical Journal
This paper considers a structure consisting of two rings of magnetic dipoles symmetrical relative to the equatorial plane as a possible model for the source of the solar magnetic field.

The First Magnetic Fields

, 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.

S-Z power spectrum produced by primordial magnetic fields

, 2011
Primordial magnetic fields generated in the very early universe are one of the candidates for the origin of magnetic fields observed in galaxy clusters.

Magnetic Field Amplification during a Turbulent Collapse

The Astrophysical Journal
The question of whether a dynamo can be triggered by gravitational collapse is of great interest, especially for the early Universe. Here, we employ supercomoving coordinates to study the magnetic field amplification from decaying turbulence during ...

Radio Polarisation Study of High Rotation Measure AGNs

Galaxies, 2017
As radio polarised emission from astrophysical objects traverse through foreground magnetised plasma, the physical conditions along the lines of sight are encrypted in the form of rotation measure (RM).

Resistive Scaling in the Magnetic Helicity-driven Inverse Cascade

The Astrophysical Journal
The inverse cascade in MHD turbulence plays a crucial role in various astrophysical processes such as galaxy cluster formation, solar and stellar dynamo mechanisms, and the evolution of primordial magnetic fields in the early Universe.

Can magnetic fields be detected during the inspiral of binary neutron stars?

, 2009
Using accurate and fully general-relativistic simulations we assess the effect that magnetic fields have on the gravitational-wave emission produced during the inspiral and merger of magnetized neutron stars.
