\nThe horizontal component of the earth’s magnetic field is zero at magnetic poles.
\n<\/section>\n
\nThe Earth’s magnetic field lines emerge from near the geographic South Pole (which is the North magnetic pole) and enter near the geographic North Pole (which is the South magnetic pole).
\n– At the magnetic poles (where a compass needle points vertically downwards or upwards), the magnetic field lines are essentially perpendicular to the Earth’s surface. Therefore, the magnetic field vector has only a vertical component, and the horizontal component is zero.
\n– At the magnetic equator, the magnetic field lines are approximately parallel to the Earth’s surface. Therefore, the magnetic field vector is primarily horizontal, and the vertical component is zero.
\n– The geographic poles (South and North Poles) are points on the Earth’s rotational axis and do not necessarily coincide with the magnetic poles. The horizontal component is generally not zero at the geographic poles unless they happen to coincide perfectly with the magnetic poles (which they do not).
\n<\/section>\n
\nThe Earth’s magnetic poles are not fixed and drift over time. The angle between the magnetic north and geographic north is called the magnetic declination. The angle between the horizontal plane and the Earth’s magnetic field line is called the magnetic dip or inclination; the dip is 90 degrees at the magnetic poles and 0 degrees at the magnetic equator.
