Earth is an island of tranquility in a sea of searing solar radiation and energetic particles, and we have the planet's magnetic field to thank. Scientists searching for early records of Earth's ...

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 ...

The compass needle points in the direction of the Earth's magnetic field, or the magnetic field of a magnet. place the plotting compass near the magnet on a piece of paper mark the direction the ...

Would a dramatic change in the Earth's magnetic field affect creatures that rely on it during migration? Late on a January night in 1993 I found myself on a beach on the Pacific coast of Costa ...

This, in turn, affects convection in the 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 drives ...

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

A new study reports that researchers have successfully used a meticulously designed cylinder to harness electricity as it ...

When the Earth’s magnetic field is strong, as it is today, the amount of carbon generated by this interaction is relatively low, but it spikes when the magnetic field weakens and allows more ...
