Spaced‐based search coil magnetometers

Journal of Geophysical Research: Space Physics, 2016
AbstractSearch coil magnetometers are one of the primary tools used to study the magnetic component of low‐frequency electromagnetic waves in space. Their relatively small size, mass, and power consumption, coupled with a good frequency range and sensitivity, make them ideal for spaceflight applications.

Use of the International Reference Ionosphere 2012 model to calculate emission frequency scale of the ionospheric Alfvén resonator

Journal of Space Weather and Space Climate, 2015
We apply the IRI-2012 version of the International Reference Ionosphere model to calculate the difference between frequencies of adjacent harmonics (frequency scale) of the ionospheric Alfvén resonator (IAR) emission.

Observations and modeling of forward and reflected chorus waves captured by THEMIS [PDF]

Annales Geophysicae, 2011
Discrete ELF/VLF chorus emissions are the most intense electromagnetic plasma waves observed in the radiation belts of the Earth's magnetosphere. Chorus emissions, whistler-mode wave packets propagating roughly along magnetic field lines from a well ...

Magnetic induction tomography using an all-optical $^{87}$Rb atomic magnetometer [PDF]

, 2014
We demonstrate Magnetic Induction Tomography (MIT) with an all-optical atomic magnetometer. Our instrument creates a conductivity map of conductive objects. Both shape and size of the imaged samples compare very well with the actual shape and size. Given

Magnetic Field Control Using an Electromagnetic Actuation System with Combined Air‐Core and Metal‐Core Coils

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
An electromagnetic manipulation system enhances magnetic field strength in the Z‐direction for 3D control of microrobots and nanoparticles. Featuring eight metal‐core coils and two air‐core coils arranged hemispherically, it ensures unimpeded workspace access and integrates imaging tools.
