Radiocarbon dating at the University of Waikato helped establish an accurate timeline, confirming the environmental impact of the magnetic pole reversal. Data from kauri trees was aligned with records ...

Recently, a research team found a new way to control the magnetic reversal in a special material called Co 3 Sn 2 S 2, a Weyl semimetal. The team was led by Prof. Qu Zhe from the Hefei Institutes ...

Earth’s magnetic north pole is on the move—and in surprising ways.With the release of the World Magnetic Model 2025, scientists reveal new details about its unpredictable journey and why it ...

A two-dimensional analytical subdomain model is proposed for a consequent-pole flux reversal (CPFR) permanent magnet (PM) machine with novel segmented magnet arrangement. Three-segment magnets with ...

One theory suggests superplumes could be leftovers from Theia, the Mars-sized protoplanet that formed the Moon after colliding with Earth. 'James Webb killer is here': NASA’s SPHEREx will scan ...

there’s no reason to think a reversal is imminent; paleomagnetic records show that the intensity drops by up to 90 percent in the process of pole-switching. We should all feel grateful that we live in ...

Magnetic materials are materials studied and used mainly for their magnetic properties. The magnetic response of a materials is largely determined by the magnetic dipole moment associated with the ...

Magnetic resonance imaging (MRI) is a non-invasive biomedical imaging technique that uses a strong oscillating magnetic field to induce endogenous atoms such as hydrogen, or exogenously added ...

Abstract: This paper proposes a new asymmetric consequent-pole flux reversal dual-PM excited machine (ACP-FRDPMM) with trapezoidal PMs (TPMs) to achieve high torque density and power factor. The ...
