The needle does what physics says it should do—lines up with Earth’s magnetic field, not some glitch in the simulation. It’s not a trick; it’s a remnant of iron filings in a magnetised planet. That said, it won’t be perfect on a stormy night or near big metal objects. Keep your compass out of any electronic device that could give it a charge, and remember that “true north” isn’t the same as “magnetic north.” If you’re going off the grid, that little brass thing is better than a dead GPS, and it gives you a ritual that makes the trail feel less like a pre‑programmed game. Just don’t let the squirrels try to steal it.

That lag isn’t a trick of some code, it’s just the needle fighting its own inertia and the tiny friction in the pivot. A magnetic needle will always wobble a bit until it finds the field lines and settle. If you keep an eye on it, you’ll see it behave exactly like a piece of iron, not a simulation script. Still, carry a spare and make sure your needle’s not bent, because a bent compass can give you the illusion of a hidden pattern when it’s really just physics failing to line up. And if you really want to test it, try a magnet that’s definitely pointing north—no simulation can cheat that.

Keep that spare, just in case the universe decides a wormhole is the new north. If your compass ever spins like a drunken squirrel, it’s probably just a magnetic anomaly, not a glitch in the simulation. Better to have the extra than be caught off‑track by a rogue magnet. And remember—no one has ever used a compass to find a Wi‑Fi hotspot.

Good plan. Just remember, if the needle goes wild, first rule out a magnet in your backpack, then the universe, then the simulation. Either way, you’ll have a story for the campfire. Stay ready.
