Simple system to measure the Earth's magnetic field

, 2010
Our aim in this proposal is by using the Faraday's law of induction as a simple lecture demonstration to measure the Earth's magnetic field (B). This will also enable the students to learn about how electric power is generated from the rotational motion.

Weak, Quiet Magnetic Fields Seen in the Venus Atmosphere. [PDF]

, 2016
The existence of a strong internal magnetic field allows probing of the interior through both long term changes of and short period fluctuations in that magnetic field. Venus, while Earth's twin in many ways, lacks such a strong intrinsic magnetic field,

Generation of By in Earth’s magnetotail with the effect of IMF By during southward interplanetary magnetic field

AIP Advances, 2021
Based on the three-dimensional compressible resistive MHD models, the Earth’s dipole magnetic field is employed to investigate IMF By penetration driven by the solar wind during southward interplanetary magnetic field (IMF) with uniform resistivity.

Effects of Self-field and Low Magnetic Fields on the Normal-Superconducting Phase Transition

, 2005
Researchers have studied the normal-superconducting phase transition in the high-$T_c$ cuprates in a magnetic field (the vortex-glass or Bose-glass transition) and in zero field.

Transport properties of iron at the Earth's core conditions: the effect of spin disorder

, 2017
The electronic and thermal transport properties of the Earth's core are crucial for many geophysical models such as the geodynamo model of the Earth's magnetic field and of its reversals.

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

Advanced Engineering Materials, EarlyView.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Calculation of the power and angular components of the geomagnetic field induction vector in the territory of Ukraine

Геофизический журнал
The study calculates the geomagnetic field induction vector power and its angular components for the territory of Ukraine for the 2024.5 epoch. We used a digital map of the ∆Bа induction module anomalies and B0, the Earth’s normal magnetic field.

The effectiveness of polder systems on peak discharge capping of floods along the middle reaches of the Elbe River in Germany [PDF]

Hydrology and Earth System Sciences, 2007
In flood modelling, many one-dimensional (1-D) hydrodynamic models are too restricted in capturing the spatial differentiation of processes within a polder or system of polders and two-dimensional (2-D) models are very demanding in data requirements and ...

Magnetic field reversals in an experimental turbulent dynamo [PDF]

, 2007
We report the first experimental observation of reversals of a dynamo field generated in a laboratory experiment based on a turbulent flow of liquid sodium. The magnetic field randomly switches between two symmetric solutions B and -B.

Near‐Infrared Emitting Lanthanide Catecholate Giant Single Crystals – Morphology Control and Photon Down‐Conversion

Advanced Functional Materials, EarlyView.
Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.
