The geodynamo model for the origin of the earth's field is lent further credence by the fact that the moon which turns around its own axis very slowly once in 28 days has a negligible magnetic field. Also, Jupiter which spins much faster than the earth has a very strong mag...
electron. The Domain theory states that if an atom's electrons are orbiting all in different directions, their magnetic fields will cancel each other out. If, however, they are orbiting in the same direction, the atom will be magnetized. A material full of these magnetized atoms is a magnet...
UT0 is the version of Universal Time measured at a specific location. Since it does not take into account distorting factors like the constant movement of the Earth's poles (polar motion), it deviates from one location to another, making it a variant of Universal Time that, strictly speaking...
Latitude is used to mark the north-south position of a location on the Earth’s surface and ranges from 0 degrees at the equator to 90 degrees at the North and South Poles. There are 180 degrees of latitude and the distance between each degree of latitude is roughly 69 miles (111 km)...
As all the molecular magic (oops, we mean science) is happening near Earth's magnetic poles, the Arctic region is ideal for viewing the aurora borealis. In fact, there is a zone in the Northern Hemisphere called the “Northern Lights Belt”, situated from 65 to 72 degrees north, which ...
Auroras are caused by energized particles from the sun slamming into Earth's upper atmosphere at speeds of up to 45 million mph (72 million kph). Earth's magnetic field then redirects the particles toward the north and south poles. The electrically charged particles then enter Earth's atmosph...
Often taller and sturdier than other poles. A high flagstaff was installed at the government building. 6 Pole Either extremity of an axis through a sphere. Flagstaff See flagpole. Pole Either of the regions contiguous to the extremities of the earth's rotational axis, the North Pole or the ...
"Even if the field becomes very weak, at the Earth's surface we are shielded from radiation by the atmosphere. Similarly as we cannot see or feel the presence of the geomagnetic field now, we most likely would not notice any significant change from a reversal," Korte said. Our technology...
General relativity is physicist Albert Einstein's understanding of how gravity affects the fabric of space-time. The theory, which Einstein published in 1915, expanded the theory of special relativity that he had published 10 years earlier. Special relativity argued that space and time are inextricab...
