This dynamic movement generates Earth's magnetic field, a protective shield against ... represent the state of the art in modeling iron’s behavior at the atomic level. These methods have yielded ...

Even with Earth’s strong magnetic field today, we’re still susceptible ... and the sudden widespread appearance of figurative art in caves around the world.

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 ...

Back in 1832, the celebrated British physicist, Michael Faraday, carried out a set of experiments designed to answer a tantalizing question: could electricity be generated by Earth's rotation through ...

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 ...

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 ...
