Evaporation Rate of Water as a Function of a Magnetic Field and Field Gradient [PDF]

open access: yesInternational Journal of Molecular Sciences, 2012
The effect of magnetic fields on water is still a highly controversial topic despite the vast amount of research devoted to this topic in past decades. Enhanced water evaporation in a magnetic field, however, is less disputed. The underlying mechanism for this phenomenon has been investigated in previous studies.

Gradient-Field-Based Force-Driven Control of a Mudskipper-Inspired Magnetic Microrobot for Intestinal Applications [PDF]

open access: yesMicromachines
Magnetically driven microrobots operating in intestinal environments face two major challenges: difficulty in traversing low-height confined spaces and limited local visibility caused by mucosal obstruction. To address these issues, this study proposes a

Magnetic Field Gradient-Based EKF for Velocity Estimation in Indoor Navigation

open access: yesSensors, 2020
This paper proposes an advanced solution to improve the inertial velocity estimation of a rigid body, for indoor navigation, through implementing a magnetic field gradient-based Extended Kalman Filter (EKF). The proposed estimation scheme considers a set

Precise Determination of Magnetic Gradient Relaxation of Coupled Atomic Spin Ensemble in Spin-Exchange Relaxation-Free Co-Magnetometer

open access: yesPhotonics, 2023
Inside a spin-exchange relaxation-free (SERF) co-magnetometer with a high-pressure buffer gas atomic cell, the magnetic field gradient causes the decoherence of atomic spins to produce magnetic-field gradient relaxation.

VELOCITY GRADIENTS AS A TRACER FOR MAGNETIC FIELDS [PDF]

open access: yesThe Astrophysical Journal, 2017
Strong Alfvénic turbulence develops eddy-like motions perpendicular to the local direction of magnetic fields. This local alignment induces velocity gradients perpendicular to the local direction of the magnetic field. We use this fact to propose a new technique of studying the direction of magnetic fields from observations, the Velocity Gradient ...

An instrument for sorting of magnetic microparticles in a magnetic field gradient [PDF]

open access: yesCytometry Part A, 2006
AbstractBackground:The goal of our bioassay technique is to demonstrate high throughput, highly parallel, and high sensitivity quantitative molecular analysis that will expand current biomedical research capabilities. To this end, we have built and characterized a magnetophoresis instrument using a flow chamber in a magnetic field gradient to sort ...

Magnetic Field Gradient Across the Flank Magnetopause

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Magnetic pressure inside the magnetopause is usually balanced with a sum of thermal plasma and magnetic pressures on the magnetosheath side. However, observations reveal that the magnetosheath magnetic field can be frequently larger than that in the ...
