A magnetic field exerts a force on particles known as the Lorentz force, according to Georgia State University'sHyperPhysics website. The force acting on an electrically charged particle in a magnetic field depends on the magnitude of the charge, the velocity of the particle, and the strength ...
Our planet is like a great magnet that have poles at the top and bottom, located near geographic poles. It create a powerful magnetic field called "the magnetosphere". It protect the Earth from big amount of solar winds and radiation. So we should be really gratefull for such protection. ...
Moon's Magnetic Mysteries: Earth has a strong magnetic field thanks to its molten core, but the moon’s magnetic field is weaker and patchy. The reason for this discrepancy remains one of the biggest lunar mysteries. Some theories suggest miniature "magnetospheres" scattered across the moon's ...
Despite its small size, Mercury still has a molten core which surprised scientists. Such a small planet should have lost its heat and solidified, but Mercury’s core churns on, generating a magnetic field (albeit one hundredth that of Earth) and an actual magnetosphere around the planet to d...
Scientists were interested to see the effect of such a close flyby on a planet. Because Mars has a weak magnetosphere, the planet was flooded with a layer of ions as the comet’spotent magnetic fieldoverwhelmed that of Mars. NASA compared the effects with those of a powerful but short-liv...
Scientists believe that a large, salty body of water on Uranus is providing the impetus for the planet’s magnetic field. They used to think that the 59-degree tilt of Uranus’s magnetic field and the 98-degree tilt of its spin axis would supply the planet with a powerfulmagnetosphere. Bu...
It starts in the upper mesophere, through all of the thermosphere and to the edge of the exosphere meeting the magnetosphere. It can be found around 50km above the Earth's surface up to 500km. What is special about the ionosphere? The ionosphere protects the planet from the extreme ...
Earth has a powerful magnetic field called the magnetosphere that protects it from solar winds. The Earth’s atmosphere is composed of 78% nitrogen and 21% oxygen. Earth is the only planet known to support life. Earth’s interior is not solid, but rather has a semi-solid or ‘squishy’ ...
Venus is one of the weirdest planets in the solar system. We explore the scorching planet in more detail with 20 interesting facts about Venus.
Facts about Ganymede Ganymede is the largest moon in the solar system, and is larger than the planet Mercury. If it were not orbiting as Jupiter’s largest moon, it could be considered a dwarf planet. Ganymede is the only moon in the solar system known to have a substantial magnetosphere....
