When an electric current passes through a metal wire, a magnetic field forms around that wire (see diagram at right ... and generators to operate. In the Earth (see image below right), the ...

This dynamic movement generates Earth's magnetic field, a protective shield against harmful solar radiation and cosmic particles. This magnetic field also influences plate tectonics and mantle ...

A diagram shows the mechanisms feeding ... outer core—the dynamo-like process that generates the magnetic field that protects life on Earth from harmful cosmic rays. "Flow in the outer core ...

The outer core is liquid iron and nickel and generates the Earth's magnetic field. And the inner core ... made from solid iron and nickel. In this diagram, the red lines represent the edges ...

Nearly two centuries after Faraday's failed attempts, scientists have demonstrated that Earth's continuous spin can directly ...

Reader Jayant Bhalerao, a college physics instructor, found the story useful in class: “We will share it with our students, so that they can appreciate how ...

Explaining the science behind the northern lights, and why 2025 could bring more opportunities to see them. #ExtremeNature ...

New research sheds light on the Earth's "innermost inner core," offering new insight into the formation of the planet and its magnetic field. From our morning news briefing to a weekly Good News ...

Most of the time, the Earth and Sun’s magnetic fields are misaligned, leaving our planet’s field less open to the aurora-causing effects of the solar wind. However, towards the equinox, the two fields ...

This discovery provides new insights into the inner core’s dynamics and its impact on Earth's magnetic field. The Earth is in a constant state of flux, and changes are constant on its surface ...

This "nano-compass" allows the microbe to passively orient itself in Earth's geomagnetic field (Figure 2). These magnetic nanoparticles ... concentration (top of the diagram) swim forward to ...
