Abstract: This paper proposes an analytical method to calculate magnetic field of nonlinear spoke-type permanent-magnet motors (STPMM) considering static, dynamic, mixed rotor eccentricities and pole ...

This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to audio speakers. Oh, and without it we’d live in eternal darkness.

In the vast, seemingly featureless expanse of the ocean, sea turtles embark on some of the most remarkable journeys in the animal kingdom. From the moment they hatch on sandy beaches and scramble ...

Physicists Prof. Dr. Ingo Rehberg from the University of Bayreuth and Dr. Peter Blümler from Johannes Gutenberg University Mainz have developed and experimentally validated an innovative approach for ...

Earth's magnetic field and oxygen levels are inextricably linked, new research suggests. The strength of the geomagnetic field has gone up in lockstep with the percentage of oxygen in Earth's ...

Earth's magnetic field and oxygen levels have increased more or less in parallel since the start of the Cambrian period (541 million to 485.4 million years ago), and both factors spiked between 330 ...

AUSTIN, Texas — Mars played by different rules than Earth when forming its magnetic field. Rather than generating magnetism with a solid core surrounded by liquid—Earth’s approach—the Red Planet ...

Ever pondered the extraordinary migratory journeys of birds? These feathered wanderers traverse thousands of kilometers, exhibiting an incredible knack for endurance and navigation that almost seems ...

Like poles will repel, unlike poles attract. And, if you break a magnet in two, you have two magnets instead of isolated North and South “monopoles.” It was once thought that charged objects ...

In a recently published article in IEEE Electron Devices Magazine the authors, I was one of them, looked at the impact of external magnetic fields on spin tunnel torque magnetic random-access memories ...
