  • causes the magnetic field
  • The iron in the core is thought to be solid, and that there is an outer liquid core that carries ionized iron that moves around the outer core in a very slow process, and that is thought what causes the magnetic field, which then is variable, and the outer core is probably asymmetrical in its motion.

  • radiation
  • The scientific observation of celestial radiation that has reached the vicinity of Earth, and the interpretation of these observations to determine the characteristics of the extraterrestrial bodies and phenomena that have emitted the radiation. (photonics.com)
  • The protective magnetic cloak cast around our planet is our shield and protector against the maelstrom of incoming radiation that rains in constantly from space. (thenakedscientists.com)
  • Without a magnetic field, our atmosphere would slowly be stripped away by harmful radiation, and life would almost certainly not exist as it does today. (theconversation.com)
  • Dmitry Budker
  • From left) Alex Pines, Dmitry Budker and Scott Seltzer led a proof-of-concept NMR experiment using a high-sensitivity magnetometer and a magnetic field comparable to that of the Earth. (lbl.gov)
  • maintain a magnetic
  • If the needle were ground into powder and the powder allowed to fall freely, the individual powder grains would maintain a magnetic North-South orientation as they fell. (grisda.org)
  • However, we know now that it is too hot inside the planet to produce and maintain a magnetic field there. (gelib.com)
  • Physicist
  • The opening was huge - four times wider than Earth itself,' says Wenhui Li , a space physicist at the University of New Hampshire who has been analyzing the data. (bibliotecapleyades.net)
  • Physicist: Magnetic fields are nothing more than the result of combining an electric field with the effects of relativity. (amazonaws.com)
  • north pole
  • Now the Federal Aviation Administration (FAA) has requested the designation be changed to 19R/1L to account for the movement of the magnetic north pole. (beforeitsnews.com)
  • What's more, we found that the magnetic lines run from the south pole towards the north pole. (scienceabc.com)
  • Evidence
  • This young-earth model explains the paleomagnetic and archeomagnetic evidence better than old-earth "dynamic" theories do. (icr.org)
  • fields
  • The event began with little warning when a gentle gust of solar wind delivered a bundle of magnetic fields from the Sun to Earth. (bibliotecapleyades.net)
  • I understand that temp over 862 degrees C there in no permanent magnetic fields. (gelib.com)
  • like why there are no magnetic monopoles, and why atoms generate magnetic fields (an orbiting electron is essentially a current loop). (amazonaws.com)
  • I have an even more difficult problem with the magnetic field (and electrostatic and gravitational fields as well). (amazonaws.com)
  • Our modified Faraday cage included a set of 3-axis coils that let us create controlled magnetic fields of high uniformity via electric current we ran through its wires. (wtop.com)
  • What is created is a self-sustained cycle of electric and magnetic fields. (scienceabc.com)
  • spin
  • The beam is pulsed at a rate determined by the local magnetic field to excite spin polarization of the sodium atoms, producing a fluorescence emission. (photonics.com)
  • blankets
  • High levels of cloud cover blankets the Earth and reflects radiated heat from the Sun back out into space, causing the planet to cool. (mondovista.com)
  • Declination
  • Contours of the magnetic declination in degrees (red) and annual change of declination (black) in minutes-of-arc per year from the AGRF 2010 model at epoch 2010.0. (ga.gov.au)

  • hemisphere
  • Since we live in mid-latitudes of the Northern Hemisphere, the environmental magnetic field in our lab dips downwards to the north at about 60 degrees from horizontal. (wtop.com)
  • John Tarduno
  • Now Rochester University's John Tarduno and his colleagues, writing in this week's edition of the journal Science , have uncovered - and extracted the magnetic signatures from - even more ancient rock samples collected in Western Australia. (thenakedscientists.com)
  • sufficiently
  • Coe and Prevot have analyzed paleomagnetism in a Miocene basalt flow at Steens Mountain in southeastern Oregon, U.S.A. Using cooling models, they obtained good estimates of the time lapse between when various levels of the basalt flow cooled to a sufficiently low temperature for the magnetic characteristics to remain fixed (be recorded). (grisda.org)
  • Faraday
  • I think the electron would orientate itself in a particular direction due to its magnetic moment, but I do not think Faraday would agree with your comment "There is a small attractive force", as an electric force is the result of a changing magnetic field, and for a stationary charge along side a wire with a steady current the magnetic field is constant.
