yes.
That is exactly what happens. The variation is up to 20
o.
The needle of a compass that works in the SH is balanced differently than one that works in the NH, due to exactly this fact that the horizontal and vertical components of the earth's magnetic field vary considerably in different locations
The compass manufacturers use 5 global zones and 5 corresponding “
magnetic balancing zones”.
You have correctly pointed out yet another Fact that demonstrates that the earth is a globe and not a platter.
