Dive into the changing forces of Earth’s magnetic field, understanding how shifts, excursions, and regional anomalies have influenced navigation, wildlife, and human technology throughout history.

Learn how to calculate and understand the force on a wire loop entering a magnetic field in this detailed physics tutorial! We break down the concepts of magnetic flux, Lorentz force, and induced ...

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

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 ...

The other discovery is the cooling of the atmosphere. Combining the observations from JWST with measurements from Voyager 2, ...

It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's happening.

In MFM, a magnetic-coated AFM probe interacts with magnetic field gradients from the sample, causing detectable forces on the probe's cantilever. To focus on magnetic interactions, MFM is often ...

Traditional magnetic separators, however, present a challenge: they generate a magnetic force that is very high near the side of the vessel closest to the magnet and decreases rapidly with distance.
