A compass for a moving Earth
The North That Moves
The north magnetic pole moved 36 kilometres in one year of observation. The needle is the same instrument; its direction depends on place and time.
In Bucharest, in 2025, magnetic north is 6.3° to the east of geographic north.
01 / two directions
The needle follows the field.
North on a map is a geometric convention. North, as a compass needle finds it, is a reading of the magnetic field — and the field changes.
The difference between those directions is called magnetic declination. In Bucharest, the WMM2025 model estimates 6.26° east in 2025 and 6.59° in 2030 — a difference of 0.33°.
On the dial
The red line moves when you change the place or year. The pale line stays with the geographic reference.
