Magnetism of the Sun/ PaleoMagnetism Flashcards
Intense magnetic field of the sun is associated with
Sunspots
Sunspots also emit hydrogen gas called
Solar Flares
is a plasma which is an ionized gas.
SOlar wind
interaction of the solar wind with the Earth’s magnetic field forms the
Magnetosphere
The
outer boundary of the magnetosphere is the
Bow shock
a region of turbulent motion
Magnetosheath
The geomagnetic field
stretches out on the night side of the Earth forming the
Magnetotail
boundary between the
Earth’s magnetic field and the solar wind is the
Magnetopause
The charged particles that penetrate the magnetopause and are trapped by the Earth’s
magnetic field form the
Van Allen Radiation Belts
Energetic particles cause ionization of molecules of nitrogen and oxygen in the atmosphere
forming an ionized region called the
Ionosphere
The ionosphere is located at an altitude of
about
50 km and 1500 km.
T or F: direction of remanent
magnetization was that of the geomagnetic field during cooling.
True
The apparatus consists of two identical small magnets mounted horizontally at opposite ends of a short
rigid vertical bar so that the magnets are oriented exactly antiparallel to each other.

is the study of the geomagnetic field recorded in dateable historic artefacts.
Archaeomagnetism
This imaginary magnet has its north pole near the geographic South Pole and its south pole near the geographic North Pole, roughly aligned with the Earth’s rotation axis.
