Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s radiation at bay. Increasingly, though, scientists are finding that this ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...

Scientists in the United States have created a small device that produces a tiny electrical signal from Earth’s natural rotation. Although the voltage is extremely small, the experiment shows that ...

One of Earth's defining features is its magnetic field. It forms a protective shield against high-energy particles ejected by the Sun and thus arguably has provided life with a safer place to grow ...

Nearly 200 years ago, a scientist named Michael Faraday tried experimenting to see whether Earth's magnetic field could help humans generate electricity for practical purposes. He concluded that ...
