Question

The angle of dip at the equator is ____.

Answer 1

The angle of dip at the equator.

1. The angle of dip is the angle between the earth's magnetic field lines and the horizontal component of the magnetic meridian.
2. It is defined as the angle in the vertical plane aligned with the magnetic north.
3. At the equator, the angle of magnetic field lines and the horizontal is perfectly parallel, thus the angle between them is $0°$.

Therefore, the angle of dip at the equator is $0°$.
