Experiments suggest that an unusual magnetic material can help harness energy from the planet’s rotation. But not everyone is ...

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 ...

Most of the time, the Earth and Sun’s magnetic fields are misaligned, leaving our planet’s field less open to the ...

A weak magnetic field likely attracted matter inward, contributing to the formation of the outer planetary bodies, from ...

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 ...

Pictures may enliven us, but other data, such as information about magnetic fields, add a huge amount to our understanding of ...

Scientists do believe the Moon had a magnetic field billions of years ago that was roughly comparable in strength to Earth’s, generated by a now-extinct molten core dynamo. This ancient field likely ...

"EZIE is the first mission dedicated exclusively to studying the electrojets," Larry Kepko, an EZIE mission scientist at NASA's Goddard Space Flight Center in Maryland, said in a statement. "It does ...

High above Earth's poles ... to observe the Zeeman effect and measure the strength and direction of the electrojets' magnetic fields. Built by NASA's Jet Propulsion Laboratory (JPL) in Southern ...
