The Earth's magnetic equator passes through Jos in Nigeria. At Jos, the
angle of variation is zero
magnetic declination is 90
angle of dip is zero
horizontal component at the Earth's field is zero
Explanation
- angle of dip is zero at the magnetic equator
- angle of variation is the same as angle of declination.
- angle of variation is the same as angle of declination.
