What causes the (detectable) magnetic field and its polarity ?
What is magnetism ?
Magnetism is one of the classes of physical phenomena that is from electromagnet is associated with current of electricity which exerts a force of attraction (or repulsion) to magnet, magnetizable or magnetic substances typically iron, nickel, cobalt, loadstone and their alloys, or from Sun or Earth is associated with the Redoña pulling out of electrons from hot gases or liquid magnetic metal. Static magnetism is detected on permanent magnet and associated with the atomic arrangement that causes Redoña pull-ability of electrons, occurring in ferromagnetic substances. Magnetism is much stronger than gravitation and it has two faces, i.e., the front and the back (well known as south pole and north pole), and therefore a ring phenomenon.
Magnetism is easier to experiment with than electricity, and yet has not explicitly explained. There are two major reasons why it is so.
1) Is the North magnetic pole seeks north magnetic pole ?
Though not critical yet, unfortunately, important to have easier mental acrobat for determining the magnetic directions.
The soldier monk Petrus Peregrinus de Maricourt started the erroneous thinking that the north-seeking pole of a compass was not a south pole but a magnetic north pole, and since then many writers were confused to tell that the north-seeking pole is the north magnetic pole (erroneously leading to a conclusion that the north magnetic pole is seeking the or attracted to the north pole of a magnet, suggesting that like poles attract each other). This leads to erroneous mental acrobat and, as a consequence, delay or even impede the scientific understanding for magnetism. The nature we have today shows us that the Earth's North Magnetic Pole is the north magnetic pole, attacted by the south pole of every magnet (e.g. loadstone), otherwise, the loadstone's north magnetic pole is not north pole (be noted that loadstone and compass' needle are both taken from the Earth).
Neither the north-seeking pole of a compass seeks South Magnetic Pole of the Earth as popularly believed on by the 2nd scientific revolutionary adherents, nor Petrus Peregrinus had told that the Earth's north magnetic pole was actually the South magnetic pole.
Although naming the poles couldn't affect the properties or nature of the magnetism, but it can disturb our clear thinking if we have two contradicting definitions ascribed to a single & the same entity at the same time & place.
2) The most disturbing, and in effect blocking us to clearly comprehend the magetism, is the erroneous model of the atom, specifically the Planetary Model, which arises from Ernest Rutherford's atom's large emptiness and Neils Borh's orbiting "planetary" electrons.
Correcting both of these errors we can have an explicit understanding about magnetism, what it is, where it originates in the atom, and what is this force.
