This video explains how magnets work and how magnetic fields are generated by the movement of electric charges. Magnetic materials influence and interact with current, motion, and force, making them ...

Deep inside the Milky Way, an invisible force is quietly holding everything together — its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, ...

Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields from the Big Bang may offer a solution.

Tiny highly uniform magnetic fields are known to pervade the universe, influencing various cosmological processes. To date, ...

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

Just as the amplified magnetic field peaked, these electrons settled again, locking in the strong field’s direction. Benjamin Weiss, an MIT professor and study co-author, explains the process like ...

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

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

The types of magnetic sensors that are currently available. How the magnetic sensors work. Applications for the different magnetic sensors. Position sensors enable a variety of functions and controls ...
