More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and ...

A notorious weak spot in Earth’s magnetic shield is growing larger and weaker. This is the conclusion of a new analysis of ...

Researchers report expansion of South Atlantic Anomaly in earth's magnetic field, but assure no imminent threat or collapse.

New satellite data show Earth’s magnetic field changing fast, with a growing weak spot over the South Atlantic.

A weak spot in Earth’s magnetic field, known as the South Atlantic Anomaly, has grown by an area half the size of Europe over ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects ...

Brownian motion in the presence of magnetic fields and under non-Markovian dynamics lies at a critical intersection of statistical physics and applied mathematics. This field examines how charged ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it encompasses both the intrinsic spin of particles and their orbital motion ...

This study focuses on the direct-drive ultrasonic resonant motors called PILine ® motors. Their direct-drive design enables ultra-low response times and highly precise positioning without any backlash ...

Magnetism is a natural force, one that works at a distance. Magnets get their force from magnetic fields created by the atoms within the metal. Magnets are useful for things like turbines we use to ...

(A) Fabrication process of the shaftless propeller-like millirobot, including positive structures’ fabrication by 2-photon polymerization (2PP), negative mold fabrication and casting process of the ...
