Concept:At the magnetic equator, the Earth’s magnetic field is parallel to the horizontal surface.
Explanation:The angle of dip is the angle between the total magnetic field and the horizontal plane.
At the magnetic equator, the field lines are horizontal, so the angle of dip is
0∘.
The horizontal component is maximum at the magnetic equator, not zero.
Angle of variation or declination is the angle between geographic north and magnetic north, and it is not necessarily zero at the magnetic equator.
Therefore, the correct property at Jos is that the angle of dip is zero.
Answer:C. angle of dip is zero
