In 1845, Michael Faraday discovered what’s known today as the Faraday Effect—which describes how light and electromagnetism are related. A new study revealed that the magnetic component of light ...

In 1845, physicist Michael Faraday provided the first direct evidence that electromagnetism and light are related. Now, it turns out that this connection is even stronger than Faraday imagined. In his ...

Here’s what you’ll learn when you read this story: The Earth’s magnetosphere protects life from deadly space radiation, but many aspects of its function remain a mystery. Scientists have long believed ...

A major dip in the Earth’s magnetic field over the South Atlantic has been puzzling scientists for over a century. An international team of researchers analyzed data collected by the European Space ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Using 11 years of magnetic field measurements from the ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

While not the most well-known name in tools, Icon has built a decent reputation for itself. The line is one of several tool brands owned by Harbor Freight and has expanded tremendously, providing hand ...

New computer simulations suggest the first magnetic fields that emerged after the Big Bang were much weaker than expected — containing the equivalent magnetic energy of a human brain. When you ...

In the evolving landscape of precision sensing, contactless potentiometers are quietly redefining what reliability looks like. By replacing mechanical wear points with magnetic sensing, these devices ...

In physics, we have a bunch of constants that are used in models to explain how the world works. These are fixed numbers that we plug into equations along with our variables. For example, the ...
