EZIE is APL’s first mission to image the magnetic fingerprints of the Earth’s auroral electrojets, electrical currents that flow between Earth and space. The mission will star a trio of CubeSats, satellites roughly the size of a small suitcase, designed to move pole to pole and ma...
inflation can also reduce the density of massive exotic particles, such as magnetic monopoles predict...
there is also pulsating aurora near the south pole," said Robert Michell, a space physicist at NASA Goddard and one of the study's authors. "Electrons are constantly pinging back and forth along thismagnetic field lineduring an aurora event." ...
but the friction and heat generation associated with magnetic levitation systems is low enough that most people think of them as being “frictionless” – even though that’s not entirely true – maglev tracks and magnetic bearings are really just “very low” friction technologies. ...
I assumed that the cores would have been marked by a drill hole to the North side of each core before boring and then I could use a compass to tell whether magnetic switching was involved or it was due to Roll-over. If by magnetic switching, then the south pole of an adjacent layer ...
s trajectory. The solar gravitational oblatenessJ2⊙and the angular momentumS⊙are responsible for additional precession rates of ~0.029” per Julian century4and ~0.002” per Julian century5, respectively. The latter perturbation, which is known as the gravitomagnetic Einstein–Lense–Thirring (ELT)...

Doctors learn a lot about their patients' health by taking their temperature. An elevated temperature, or fever, can be a sign of illness. The same goes for plants, but their temperatures on a global scale are harder to measure than the temperatures of i
NASA has yet again postponed the launch of the James Webb Space Telescope (JWST) that was supposed to happen on Tuesday after engineers discovered a communications glitch “between the observatory and the launch vehicle system.” This was updated in a blog from the agency. Thomas Zurbuchen,...
Machines 10 and 12 may be constructed adjacent to each other in a single housing with identical or different pole arrangements. Alternately, the double-induction machine may be constructed so as to place the stator and rotor windings of the two machines in the same magnetic structure but with ...
