The magnitude of the angle of dip at the equator is
Answer Details
The angle of dip, also known as the magnetic inclination, is the angle between the horizontal plane and the total magnetic field vector at a particular location on Earth. At the equator, the angle of dip is zero degrees because the magnetic field lines run parallel to the Earth's surface at this location. This means that there is no component of the magnetic field vector that points vertically downwards, so the angle of dip is zero.
Therefore, the correct answer is option B: 0 Deg.
