WebThe needle of a compass is itself a permanent magnet and the north indicator of the compass is a magnetic north pole. The north pole of a magnet will tend to line up with the magnetic field, so a suspended compas needle will rotate until it lines up with the magnetic field. Unlike magnetic poles attract, so the north indicator of the compass ...
WebA compass contains a small bar magnet on a pivot so that it can rotate. The compass needle points in the direction of the Earth’s magnetic field, or the magnetic field of a magnet. WebThe magnetic field is described mathematically as a vector field. This vector field can be plotted directly as a set of many vectors drawn on a grid. Each vector points in the direction that a compass would point and has length dependent on the strength of the magnetic force.
WebTrue north is a fixed point on the globe. Magnetic north is quite different. Magnetic north is the direction that a compass needle points to as it aligns with the Earth’s magnetic field. What is interesting is that the magnetic North Pole shifts and changes over time in response to changes in the Earth’s magnetic core. It is not a fixed point.
