Development and application of a global magnetic field evolution model for the solar corona [PDF]

, 2009
Magnetic fields are fundamental to the structure and dynamics of the Sun’s corona. Observations show them to be locally complex, with highly sheared and twisted fields visible in solar filaments/prominences.

Gradient phase and amplitude errors in atomic magnetic gradiometers for biomagnetic imaging systems

iScience
Summary: The cross-axis projection error (CAPE) caused by residual magnetic fields has recently attracted widespread attention. In this study, we propose a more specific theoretical model and expand the CAPE in gradient measurements. We first report that

Extended homogeneous field correction method based on oblique projection in OPM-MEG

NeuroImage
Optically pumped magnetometer-based magnetoencephalography (OPM-MEG) is an novel non-invasive functional imaging technique that features more flexible sensor configurations and wearability; however, this also increases the requirement for environmental ...
