The geomagnetic field is currently weakening, possibly because of a growing patch of reverse-alignment in the liquid core deep beneath Brazil and the South Atlantic. According to Tarduno, the strength of Earth's magnetic field "has been decreasing for at least 160 years at an alarming rate, ...

the hydrogen atom has the weakest nucleomagnetic field strength,
This demonstrates that the applied field strength during synthesis plays a significant role in the formation of these two minerals, even in weak Earth-like fields. Based on our results and the different formation mechanisms of hematite and goethite, we infer that an applied magnetic field should ...
Scientists already know thatmagnetic north shifts. Once every few hundred thousand years the magnetic poles flip so that a compass would point south instead of north. While changes in magnetic field strength are part of this normal flipping cycle, data from Swarm have shown the field is starting...
Assuming that each planet's magnetic field has the simplest structure, a dipole, we can characterize the magnetic properties by noting the equatorial field strength (B0) and the tilt of the axis with respect to the planet's spin axis. For all the magnetized planets other than Mercury, the ...
Remarkably, maximum rates of directional change reach ~10掳yr, typically during times of decreasing field strength, almost 100 times faster than current changes. Detailed analysis of the simulations and a simple analogue model indicate that extreme directional changes are associated with movement of ...
Special attention has also been paid to the field of biomedical applications for implant design and stent manufacturing due to the biodegradable nature of Mg [46,47]. Mg-Zn-Zr alloy exhibited good strength and ductility because of grain refinement due to Zr addition [48]. However, its ...
Could it be that Earth's temperature rises when it's magnetic field decreases? As the flows of Earth's metallic core change, it's magnetic field changes. And currently the magnetic field is decreasing. This decreasing in magnetic field allows more "solar energy" to arrive at the planet and...
"That patch may be largely responsible for the decreasing magnetic field," Tarduno said. The patch is like an eddy in a stream, he said. As for what causes the eddy, it may be something odd about the mantle right abovethe corein that location, he said. The mantle under southern Africa...
