What is the primary source of electricity in the U.S.? What is biofuel? What is a biofuel? What are the units of power? What can cobalt-60 be used for? What is an excimer laser used for? Wind power generates what kind of pollution?
As the solar wind approaches Earth, it’s deflected by Earth’s magnetic field and diverted north and south toward the magnetic poles. The interaction between the solar wind and the magnetosphere generates beams of electrons. These electrons collide with atoms and molecules within the ionosphere ...
the magnetic poles.The interaction between the solar wind and the magnetosphere generates beams of electrons.These electrons collide with atoms and molecules within the ionosphere near Earth’s magnetic poles.The collisions rip apart molecules and excite atoms.Thus, oxygen and nitrogen atoms in the ...
The Earth's magnetic field generates the magnetosphere that surrounds the Earth. Interaction of the solar wind with the magnetosphere causes the northern and southern lights known as the Aurora Borealis and Aurora Australis. The Earth's magnetic field also impacts the iron minerals in lava flows. ...
of Induction, which is the basis for electromagnets, electric motors and generators. A charge moving in a straight line, as through a straight wire, generates a magnetic field that spirals around the wire. When that wire is formed into a loop, the field becomes a doughnut shape, or a ...
What phenomena occur in the thermosphere? The ionosphere is where the sun’s radiation causes particles to be electrically charged. This is why the term “ion” originates in the ionosphere. As such, this is where theaurora borealisgenerates spectacular displays of light. Solar winds travel down...
Originating from Earth’s core and atoms themselves, magnetism is the invisible force that shapes our everyday lives. Here’s how magnets actually work.
Urn, on Earth, the main source of naturally occurring VLF emissions is lightning, which generates a pulse of radio waves every time it flashes. Yes, Laura. Student: Since you almost always get lightning with thunderstorms, we can pick up VLF waves pretty often, right? You just have to wai...
When an electric charge cuts across a magnetic field it generates an electric current (see How Electricity Works). As these currents descend into the atmosphere along the field lines, they pick up more energy. When they hit the ionosphere region of the Earth's upper atmosphere, they collide ...
A study using MESSENGER data showed that Mercury generates more low-frequency solar wind waves when farther from the Sun. This finding supports the idea that the Sun’s magnetic field weakens with distance. Mercury is special. As the closest planet to the Sun, it occupies a region where the...
