The spelling of "magnetic north" can be explained using the International Phonetic Alphabet (IPA). The first syllable, "mag," is pronounced /mæɡ/, with a short "a" sound and a hard "g" sound. The second syllable, "net," is pronounced /nɛt/, with a short "e" sound and a "t" sound at the end. The final syllable, "ic," is pronounced /ɪk/, with a short "i" sound and a "k" sound at the end.

Magnetic north refers to the direction indicated by a compass needle, which is towards the Earth's magnetic north pole. It is the point on the Earth's surface towards which the north-seeking end of a magnetic compass needle points. This direction is generally close to but not exactly aligned with true north, which is defined as the direction towards the Earth's geographic North Pole.
Earth's magnetic field is created by the movement of molten iron within the outer core of the planet. As a result, the magnetic field is not fixed but constantly changing. Over long periods of time, the position of the Earth's magnetic poles can shift, and this causes a variation in the alignment of magnetic north and true north. Currently, the Earth's magnetic north pole is moving towards Russia at a rate of approximately 10 kilometers per year.
The concept of magnetic north is crucial for navigational purposes, allowing travelers to determine their direction and orient themselves. By aligning a compass needle with magnetic north, individuals can easily establish their course and maintain a sense of direction. However, it is important to note that magnetic north does not remain constant and therefore should be regularly updated to account for any changes in the Earth's magnetic field.
The word "magnetic" comes from the Latin word "magnēticus", which in turn derives from the Greek word "magnētis lithos". "Magnētis lithos" refers to a type of rock called "lodestone" or "magnetite", which has natural magnetic properties. "North" comes from the Old English word "norþ", which is related to the Dutch word "noord" and the German word "nord". The term "magnetic north" combines these two elements, referring to the direction of the Earth's magnetic field in the northern hemisphere.
