Topological insulators (TIs) are among the hottest topics in condensed matter physics today. They're a bit strange: Their ...

Straight solenoid (only qualitative treatment), force on a moving charge in uniform magnetic and electric fields. Force on a current-carrying conductor in a uniform magnetic field, force between ...

Additionally, an equivalent transformation method is introduced to emulate the non-uniform magnetic field arising from rotor eccentricity. The validity and correctness of the proposed models are ...

the magnetic north pole’s position is determined by Earth’s magnetic field, which is in constant motion. Over the past few decades, magnetic north’s movement has been unprecedented — it ...

The reversal could actually have a beneficial effect on Earth. The sun is on the verge of a significant event: a magnetic field reversal. The sun undergoes such a reversal every 11 years ...

Altermagnetism could transform electronics, offering faster, more efficient, and sustainable alternatives to traditional ...

A massive and evolving weak spot in Earth’s magnetic field, known as the South Atlantic Anomaly (SAA), has caught the ...

However, this magnetic shield is far from uniform. “The magnetic field is actually a superposition of fields from many current sources,” explained NASA geophysicist Terry Sabaka in 2020.

Scientists have discovered that the 'weak spot' in Earth's magnetic field is growing, allowing harmful radiation to come closer to our planet's surface. The region, known as the South Atlantic ...
