Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

This paper mainly proposes an improved advanced angle field weakening control strategy for multi-phase PMSM. Firstly, voltage vector reference limit of multi-phase PMSM is analyzed and calculated.

The transient field-frequency domain of magnetic dipole in a two-layered conducting Earth has been studied. It is obtained as a summation of waveguide modes plus contributions from branch cuts in the ...

Neanderthals have long been the subject of intense scientific debate. This is largely because we still lack clear answers to ...

Scientists explore the mystery of Neanderthal extinction. A new theory links their disappearance to the Laschamp event. This ...

Could cosmic radiation from a magnetic pole shift explain Neanderthal extinction? A new study from the University of Michigan has reignited a long-standing debate surrounding the mysterious extinction ...

As per NASA's Earth Science News Team, scientists argue that the magnetic field is very important for protecting the atmosphere from erosion through energetic particles rising from the Sun. However, ...

In 2021, researchers predicted that a geomagnetic reversal could lead to mass extinctions and climate chaos—not from the flip itself, but from the collapsing magnetic field. With Earth’s shield ...

Australia’s iconic bogong moths are the first creatures other than humans and some birds known to navigate by the night sky.
