A survey of high-speed electron flow observed by NASA satellites in the Earth’s magnetotail is presented and related to the process of magnetic field line reconnection and particle acceleration.

S cientists have found that it’s possible to generate electric power from Earth’s rotation through its own magnetic field ...

the angle at which magnetic field lines intersect the Earth. The turtles use these two pieces of information, which vary at every point on the planet's surface, as navigational markers that help ...

Such reversals in the Earth's magnetic field, they'd tell you ... but in geologic terms they happen all the time. As the time line at right shows, hundreds of times in our planet's history ...

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 ...

A 3.7-billion-year-old record of our planet's ancient magnetism has been unearthed, providing evidence that Earth's magnetic field already existed very early in history. This discovery, however ...

The strength of the Earth’s magnetic field ranges between 25,000 and 65,000 nano-Tesla (nT) with values of 31-58,000 nT between the equator and 50 degrees latitude.

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...
