The north magnetic pole (NMP) is the point at the Earth's surface where the geomagnetic field is directed vertically downward. It drifts in time as a result of core convection, which sustains the Earth's main magnetic field through the geodynamo process. During the 1990s the NMP drift ...

What will be the orientation of a freely moving magnetic needle near the magnetic poles of the earth? View Solution Assertion (A): It is not necessary that every magnet has one north pole and one south pole. Reason (R ): It is a basic fact that magnetic poles occur in pairs ...
Even the Earth, in fact, has a pair of poles: the north and south poles. Overview of Magnetic Poles Magnetic poles are sections on a magnet where the magnetic field is the strongest. They are found on opposite ends. The north pole is found on one end of a magnet, whereas the south ...

Step-by-Step Solution:1. Definition of Magnetic Poles: - Magnetic poles refer to the two distinct ends of a magnet. Each magnet has a north pole and a south pole.2. Identification of Poles
those in a bar magnet, the magnetic moment (m) is defined as the strength of the poles (p) multiplied by the distance between the poles (L), which can be represented by the equation m = pL. The direction of the moment points from the south pole of the magnet to its north pole. ...
