Learn how to perform a vector magnetic field calculation using two current-carrying wires in this clear, step-by-step physics tutorial. We break down key concepts like the Biot–Savart law, vector ...

Researchers have identified a period of sluggish magnetic field flipping for planet Earth, some 40 million years ago – ...

Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.

Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation.

RIKEN physicists have found a magnetic material that converts heat into electricity with high efficiency, making it promising for use in energy-harvesting devices. The work is published in the journal ...

Earth’s magnetic field can linger in a weakened, unstable state for tens of thousands of years before fully flipping.

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

A new radio survey reveals that the Milky Way’s magnetic field is intricate, widespread, and deeply connected to how the galaxy is organized.
