  • Less than one hundred years ago, the south pole of Earth was a land of utter mystery. (scienceblog.com)
  • It happens every 300,000 years or so on Earth in synch with-what? (scienceblog.com)
  • Hartmann's research team has been inspecting magnetometers (magnetic field sensors) for years and they have effectively designed these devices for a complete range of applications. (azosensors.com)
  • The new study indicates that about 10 -13 J of energy is transferred per cubic metre every second in this region of Earth's magnetic environment. (esa.int)
  • That's all great on paper, but until recently physicists haven't been able to actually observe this force in action. (sciencealert.com)
  • From the observed direction of interplanetary magnetic field lines (or "interplanetary lines of force"), we believe this field comes from the Sun, carried by magnetic field lines dragged out by the solar wind . (phy6.org)
  • The thickness of the field lines is a measure of the local magnetic field strength. (mpg.de)
  • En route, the prominence ran into a snarl of magnetic field lines, causing them to reconnect in a distinct X shape. (scitechdaily.com)
  • An optional activity, to draw the expected shapes of interplanetary magnetic field lines. (phy6.org)
  • Using this 'law of field line preservation', we will now derive the shape of interplanetary magnetic field lines. (phy6.org)
  • The magnetic field at all these points is already so weak that the solar wind overpowers it and shifts its field lines, while its own motion--radially outward--remains unchanged. (phy6.org)
  • When it occurs in flares, the result is a bright flash - with effects that can reach Earth. (nasa.gov)
  • fluctuations in temperature, noise, frequency and motion can lead to a condition physicists refer to as decoherence, a leakage of energy that derails calculations. (cio.com)
  • an electrostatic field on Earth observed to be a magnetic field by orbiting astronauts-these are some situations where physicists employ tensors. (waterstones.com)
  • Currently, two different instruments are used to measure the magnetic wavelength spectrum in space, the fluxgate magnetometer and search coil, said George Hospodarsky, a UI associate research scientist. (dailyiowan.com)
  • Instruments from the Birkeland Centre for Space Science at UiB will soon be launched to the International Space Station (ISS), to measure gamma-ray flashes on Earth. (uib.no)
