The Earth's magnetic equator passes through Jos in Nigeria. At Jos. the
angle of variation is zero
magnetic declination is 90o
angle of dip is zero
horizontal component of the Earth's magnetic field is zero
הֶסבֵּר
At the magnetic equator, the angle of dip (or inclination) is zero because the magnetic field lines are horizontal.
