Physical Model of the Earth’s Magnetic Field

open access: yesVestnik Permskogo Universiteta: Seriâ Geologiâ, 2018
The article considers the feasibility of generation inside the Earth the electric current, which is the source of its magnetic field. The analysis of the existing kinematic models of electric current generation in the Earth's core is presented.

Time scale of the largest imaginable magnetic storm [PDF]

open access: yesNonlinear Processes in Geophysics, 2013
The depression of the horizontal magnetic field at Earth's equator for the largest imaginable magnetic storm has been estimated (Vasyliūnas, 2011a) as −Dst ~ 2500 nT, from the assumption that the total pressure in the magnetosphere (plasma plus magnetic ...

Simple system to measure the Earth's magnetic field

open access: yes, 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.

Effects of Processing Conditions of a Ball‐Milled Fe65Co35 Soft Ferromagnetic Alloy on the Structural, Thermal, and Magnetic Properties

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
In the present work, synthesizing nanoscrystalline Fe65Co35 alloy by mechanical alloying is focused on, adding cyclohexane (C6H12) acting as a process control agent (PCA). PCAs are effective in favoring nanostructured alloys with uniform grain size. The production of this type of alloy is a promising approach to tune the magnetic hardness in Fe65Co35 ...

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

open access: yesHydrology 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 ...

Charge Determination of High Energy Electrons and Nuclei by Synchrotron Radiation with AMS [PDF]

open access: yes, 1998
We investigate the possibilities to identify the charge of TeV electrons and PeV nuclei using their synchrotron radiation in the earth's magnetic field. Characteristics of synchrotron radiation photons are evaluated and methods of detection are discussed.

Functional Recycling and Reuse of Nd–Fe–B Permanent Magnets from Various Waste Streams for a more Sustainable and Resilient Electromobility

open access: yesAdvanced Engineering Materials, Volume 27, Issue 7, April 2025.
Due to the increasing demand and growing importance of resilient and sustainable supply chains, the use of recycled and reused Nd–Fe–B magnets in e‐mobility applications such as Pedelecs, e‐Scooters, and Hoverboards is being investigated. It can be shown that the corresponding motors with recycled magnets do not exhibit any loss of performance while at

Variability of magnetic field spectra in the Earth's magnetotail [PDF]

open access: yesNonlinear Processes in Geophysics, 2009
We investigate the variability of magnetic fluctuation spectra below 1 Hz in the Earth's plasma sheet using specially selected long observation intervals by Geotail spacecraft. The spectra can be generally described by a negative power law with two kinks.
