Likewise, a wire passing through a magnetic field creates an electric current within the wire. This is the basic principle that allows electric motors and generators to operate. In the Earth (see ...

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 ...

If it weren’t for the magnetic field that surrounds our planet, blocking cosmic radiation and solar wind, Earth would likely have little atmosphere to speak of. Life (at least of the human variety) ...

The World Magnetic Model predicts shifts in Earth's magnetic field using data from satellites like ESA’s Swarm mission. Einstein was wrong? Scientists may have found Dark Matter’s first signal ...

NASA's EZIE will study auroral electrojets, powerful electrical currents in Earth's atmosphere. This will improve space ...

A perfectly preserved ancient tree fossil offered scientists an unprecedented view into a moment 42,000 years ago when the Earth’s magnetic field went haywire. The compelling 2021 study tells ...

While shifting is not a rare occurrence, the pole is moving both faster and differently than it was before, raising questions about the planet's magnetic field. If the Earth's field is disrupted ...

The sun periodically ejects huge bubbles of plasma from its surface that contain an intense magnetic field. These events are ...

High above Earth's poles, intense electrical currents called electrojets flow through the upper atmosphere when auroras glow in the sky. These auroral electrojets push about a million amps of ...

As this material is often conductive, it will likely affect the Earth’s magnetic field, as argued by [Sierra Solter-Hunt] in a pre-publication article. Although the speculation by [Sierra] can ...

The Sun periodically ejects huge bubbles of plasma from its surface that contain an intense magnetic field. These events are called coronal mass ejections, or CMEs. When two of these ejections collide ...

Magnetotactic bacteria synthesize magnetic iron nanominerals, which function as tiny compasses that allow the microbes to navigate using Earth's geomagnetic field. Earth's iron cycle is a very ...
