I think it will have more than that...
Longitude and Latitude are artifical lines that have no physical existance
The earth will be a big magnetic field passing through an even bigger one. I am betting the bigger one wins
while we are in the same hemisphere we are actually getting a boost from the galaxy’s magnetic field- once we cross over, who knows how long ‘til we feel a braking effect.
And even the tiniest amount will shift all that water... some place
The galactic magnetic field, like the earth’s magnetic field, is weakest at the equator.
