A small, round piece of asteroid Ryugu (sample #91), called “S-lunar,” contains tiny particles (less than 1 mm) that will allow planetary scientists to study the magnetic signature of the early solar ...

Samples from Ryugu, a small, near-Earth asteroid, preserve natural remanent magnetization (NRM) from the early history of the solar system. However, despite multiple studies, there is currently no ...

Paleomagnetic analysis of 28 Ryugu asteroid particles reveals stable magnetization acquired within millions of years of solar ...

To uncover the history of our solar system, it is necessary to study the dynamic evolution of the ancient solar nebula materials. These materials ...

Abstract: Demagnetization is one of the most important and major faults in permanent magnet (PM) machines caused by harsh operating conditions, physical damage, high-temperature, aging, or an inverse ...

Abstract: In this paper, to mitigate the risk of irreversible motor demagnetization during short-circuit faults, a demagnetization assessment and design optimization approach is proposed for the ...
