Magnetism is a force of nature produced by moving electric charges. Sometimes these motions are microscopic and inside of a material known as magnets. Magnets, or the magnetic fields created by moving electric charges, can attract or repel other magnets, and change the motion of other charged ...

Variations of rainfall The definition of "Earth's magnetic field"is a geomagnetic field that starts in the core of the Earth emanates out into space forming amagnetosphere. Ageomagnetic fieldis an amalgamation of separate fields that all originate from different sources all over the Earth. The ...
Earth's magnetic field originates in the outer core and extends out into the magnetosphere — a region of space that helps protect Earth from space weather.
The meaning of MAGNETIC FIELD is the portion of space near a magnetic body or a current-carrying body in which the magnetic forces due to the body or current can be detected. How to use magnetic field in a sentence.
core and finds it as low as 1010C.G.S. units. If this value is correct, an intense thermal convection must be maintained in the core by the heat development of radioactive impurities, even if the amount of the latter is exceedingly small compared to their concentration in the earth's ...
Armed with magnetometers for measuring magnetic fields, researchers also mapped out the magnetic orientation of seafloor rocks — how their iron-bearing minerals are oriented relative to Earth’s field. From Science News Cosmologists have no end of ideas, but one overlooked option is the possible ...
