Sun rises in the North and sets in the South.

I'm still trying to work out how rotation of the planet and the magnetic poles are aligned to get that effect.

Is that even possible?

[AlyssaThalon]

All you need to know is that the axis of rotation is in alignment with the orbit, no math or other weirdness needed.

As for if that is the truth in raft, only the compass can tell you that.

If you were to look at a compass during the process of a geomagnetic reversal, there could be a moment where it points east, giving the perception that the sun is rising in the north. I don't know how that fits into the story though since the history of this happening on earth doesn't align with previous global warmings and there is no evidence of it affecting climate either. I'm just gonna have to blame the Selene Research Facility.

They merchant would get more traffic if they were down by the water rather than way up on the mountain.

Selene seems to have been a response to the water already rising. The notes mention it being built to research reactors for the floating cities.

Before the notes were changed for chapter 3 there were hints that something big happened, so I'll blame that.

And to be more clear for the OP, the magnetic and rotational poles don't have to align. in fact they don't do so now, depending on where you are in the world if you want true north you have to apply a correction to your compass.

It takes just a little understanding of geometry, magnetism, and astrophysics to understand that this is utterly impossible.

I also steamed north-west from Varuna to get to Temperance, which Sparrow describes as being southerly.

They could fix the compass just by changing the texture so that the east direction points to sunrise. There are no other indicators that name that direction NORTH. Problem solved.

But they really shot verisimilitude in the foot by adding as polar region. To say nothing of the whole "global warming flooded the planet!" while there's still icecaps. They really weren't even trying to keep the setting coherent at that point.

Oooooo..... a new word......

"verisimilitude"

..... nice word.

A few months back I ran into a discussion of realism versus verisimilitude. We don't want a realistic world, but we still want a world that has a sense of reality and consistency. It cuts down on the "why are you complaining about the world being unrealistic" trolls.

Well, we know it's unrealistic. That's the fun part, comparing them.

One thing I noticed is that the raft drifts "north" by default, which is probably more what the compass is intended to indicate.

But yes, the magnetic poles can move, for example, the North Magnetic Pole could somehow end up in southern Hawaii and the South Magnetic Pole in western Botswana. They're not even direct antipodes, actually. And the magnetic poles are actually the reverse, the MNP is actually the magnetic field's SOUTH pole, technically speaking.

Who tells you these things? You really need to stop listening to them.

Uranus' magnetic axis is almost 60 degrees from its rotational axis, which means a compass will behave more like it does in Raft than it does on Earth. There is nothing in theoretical or experimental physics that says the magnetic axis can't be 90 degrees from the rotational axis.

Here's a nice visualization from NASA, where the small blue arrow is the rotational axis and the small cyan arrow is the magnetic field axis.

Ah, but the dynamics of it, as the planet revolves on it's axis. My question is; Does the magnetic axis rotate along with the surface or does it remain fixed in a particular direction as the "surface" (if you can fairly define a 'surface' on Uranus) rotates?

So, what does that translate to from the perspective of a person on a fixed location on the surface? Too many rotating colored arrows for me.

In an Doku about the Moon they had say, that without the Moon the Earth Axis will swinging around like an low rotating Gyros Toy. And that the Gravity of Moon and Sun hold the Axis stable.
But the Moon rotatet not around the Center of the Earth. Earth and Moon rotate around a Point that is in the Mantle of the Earth (Bary Center).

They have not clearly say what this do with the Earth, but I belive, that only the Mantle is stable and the Core of the Earth is swinging around.

In the last 5000 Years the magnetic Northpole was a few time down to 70 degree of the Geographical Northpole.
Wikipedia says last Time around 1900 in North Canada.

If the magnetic Pole can came closer to the Äquator then the compas can show in the direction of the sunrise ore dawn.

But maybe the elliptical form of the Earth (Spheroid) will stop such a move.
Ore the Core will take mantle whit him and move the Axis of the Mantle so that Europe can come closer to the Axis . (that what I believe what was happen in the last "Ice Age", ore the Sinflood in the Bible).
An other good description how this feels when this happend, is in my Eyes the foaming of the Milk Ocean from the Hindumythologie.

Critic? No, I actually have a degree in physics. Uranus actually behaves in a way you claimed as "impossible." But, I guess you'll never learn the truth, because you blocked it.

The magnetic axis does rotate with the planet. It's the same as Earth, but magnetic north is now about 60 degrees off from rotational north. It may be challenging to understand since we're so used to Earth and how it works, but Earth is only one planet of surely, trillions. If we lived on Uranus, then we would have just evolved a society that understands magnetic north is about East on the globe. Who knows how we would have made our compasses. Instead of being used to north at the top of the compass, maybe we would have used East instead.

As if physics and other forms of science work on this world also....I think it is good for a giggle.
