Declinação Magnética

Definição

A declinação magnética é o ângulo entre o norte verdadeiro (geográfico) e o norte magnético em um determinado local, expresso em graus leste ou oeste.

Explicação

Earth's magnetic north pole does not coincide with its geographic north pole, causing compasses to deviate from true north by an amount that varies by location and changes over time. In 2024, magnetic declination in London is approximately 0°, while in Los Angeles it is about −11° (west). Hikers, pilots, and surveyors must apply this correction to convert compass readings into accurate true bearings.
