The magnetic north pole, located in the Canadian Arctic, attracts the north-seeking end of a compass needle, which is actually the south pole of the magnetized needle itself, following the scientific rule that opposite poles attract. How the Needle Aligns A compass needle is typically made of lightweight magnetic material, such as magnetized steel or iron.
True North Versus Magnetic: Understanding Declination
Magnetic needle responds to field direction. This field resembles that of a massive bar magnet, tilted slightly from the planet’s rotational axis.
Advanced compass usage requires adjusting for this declination to achieve true north alignment. The housing is often filled with a damping fluid that eliminates oscillation, allowing the needle to settle quickly.
True North Versus Magnetic: Understanding Declination
The Earth as a Giant Magnet The fundamental principle behind compass functionality lies in the Earth’s magnetic properties. The reason a compass works boils down to the interaction between a magnetized needle and the Earth’s own magnetic field.
