Earth's Magnetic Field

  1. 1.  Earth’s Magnetic Field is also known as Geomagnetic Field.
  2. 2.  It extends from the Earth’s interior to where it meets the Solar wind, a stream of charged particles emanating from the Sun.
  3. 3.  Earth’s magnetic field serves to deflect most of the solar wind.
  4. 4.  Earth's magnetic field, predominantly dipolar at its surface, is distorted further out by the solar wind.This is a stream of charged particles leaving the Sun's corona and accelerating to a speed of 200 to 1000 kilometres per second.They carry with them a magnetic field, the interplanetary magnetic field (IMF).
  5. 5.  The area of space near an astronomical object in which charged particles are controlled by that object's magnetic field.
  6. 6.  It is a donut-shaped region containing low-energy charged particles that could be found inside the Magnetosphere.
  7. 7.  The distance at which a planet can withstand the solar wind pressure is called the Chapman– Ferraro distance.
  8. 8.  The area of the magnetosphere wherein the pressure from the planetary magnetic field is balanced with the pressure from the solar wind.
  9. 9.  Opposite the compressed magnetic field is the magnetotail, where the magnetosphere extends far beyond the astronomical object.
