Question

What is the angle of dip at magnetic poles and magnetic equator?

Answer 1

Magnetic equator:

Isoclinic lines constitute contour lines whereby the dip observed at the Earth's surface is comparable. The magnetic equator or aclinic axis seems to be the location of the zero-dip points. At the equator, the dip needle rests horizontally at an angle of zero degrees.

The angle of dip:

1. The magnetic dip, commonly known as the angle of dip, seems to be the angle formed by the earth's magnetic field lines well with horizontal. It's also characterized as the angle seen between the local magnetic field as well as the horizontal throughout the vertical plane associated with the magnetic north.
2. The dip angle would be measured between zero and $90\mathrm{degrees}$. Whenever the magnetic field anywhere at measuring points downward to the ground, it shows that perhaps the dip's angle seems to be positive. The magnetic field points upwards when the angle of dip is negligible.
3. The angle of dip varies from location to location upon that earth's surface, providing knowledge about the availability of the earth's magnetic field. Infield mapping especially in geological fields, the angle of dip plays a vital function.
4. The angle that the lines of force make with the Earth's surface at any given place is called the angle of dip and varies from $0$ degrees at the magnetic equator, to virtually $90$ degrees at the magnetic poles.
   The lines of force around the magnetic equator of the Earth are perfectly horizontal. So the magnetic needle will become horizontal there. Thus, the angle of dip at the magnetic equator of the Earth will be $0$ degrees.

Therefore, the dip runs from either the South Magnetic Pole to $(-90)\mathrm{degrees}$ throughout the North Magnetic Pole $(+90)\mathrm{degrees}$.
