תרשים סכמטי של כדור הארץ

  • A = ציר הסיבוב של כדור הארץ (מסומן בקו ירוק)
  • A1 A2 = הקטבים הגאוגרפיים - הנקודות שבהן "חותך" ציר הסיבוב את פני כדור הארץ.
  • הגלעין החיצוני (נוזלי) (מסומן בצבע אפור) - שכבה בכדור הארץ שבה נוצר השדה המגנטי, על פי w:he:תאוריית הדינמו.
  • B = ציר הדו-קוטביות (מסומן בקו כחול) - הציר המגנטי הדו-קוטבי, המדמה מעין מוט מגנטי, שחלקו הצפוני הוא מגנט שמבחינה פיזיקלית נחשב ל"דרומי" (מסומן ב-‎S‏ = South = דרום), ואילו חלקו הדרומי נחשב ל"צפוני" (‎N‏ = North = צפון) מבחינה פיזיקלית. כיום, הזווית בין ציר זה לבין ציר הסיבוב של כדור הארץ היא 11.3°.
  • B1 B2 = הקטבים הגאומגנטיים - הנקודות שבהן "חותך" ציר הדו-קוטביות את פני כדור הארץ.
  • קווי השדה המגנטי (קווים שחורים דקים) - מתארים את כיוון השדה המגנטי מחוץ לגלעין.
  • C1 C2 = הקטבים המגנטיים - הנקודות שבהן קווי השדה המגנטי (מסומנים בקווים שחורים) מאונכים לפני כדור הארץ (זווית של 90° בדיוק בגובה פני הקרקע). הקטבים המגנטיים אינם חופפים לקטבים הגאומגנטיים.

Schematic diagram of the Earth

  • A = Earth's axis of rotation (marked with a green line)
  • A1 A2 = the geographical poles - the points at which the axis of rotation "cuts" the axis of rotation of the earth.
  • The outer core (liquid) (marked in gray) - a layer on Earth where the magnetic field is formed, according to the dynamo theory.
  • B = Bipolar Axis (marked with a blue line) - The bipolar magnetic axis, which simulates a kind of magnetic rod, the northern part of which is a magnet that is physically considered "southern" (marked with S = South = South), while its southern part Is considered "North" (N = North = North) physically. Today, the angle between this axis and the axis of rotation of the Earth is 11.3 °.
  • B1 B2 = the geomagnetic poles - the points at which the bipolar axis "cuts" the earth's surface.
  • Magnetic field lines (thin black lines) - describe the direction of the magnetic field outside the nucleus.
  • C1 C2 = The magnetic poles - the points at which the magnetic field lines (marked with black lines) are perpendicular to the Earth (an angle of 90 ° exactly at ground level). The magnetic poles do not overlap with the geomagnetic poles.
