Question

What is the Angle of Dip?

Answer 1

The angle of dip:

1. The angle formed by the total field vector with respect to the horizontal plane, which is positive for vectors underneath the plane is the angle of dip.
2. The angle of dip differs significantly from location to location, revealing relevant data about the locomotion of the earth's magnetic field.
   Whenever the magnetic field is pointing downhill, the angle of dip is said to have been positive. The angle of dip is stated to be negative ($-$) whenever the magnetic field was indeed pointing upwards.
3. Whenever the dip needle seems to be horizontal, the angle of dip seems to be $0°$, when it is vertically, the angle of dip is $90°$. The angle of dip is 45° whenever the horizontal, as well as vertical components of the earth's magnetic field, are approximately equivalent.

Therefore, the angle of dip somewhere at the equator exactly $0°$ also because the force's magnetic lines seem to be entirely horizontal here anyway, as well as the magnetic needle remains horizontal.
