Attempts to obtain a magnetic monopole by sawing a magnet into two parts have not been successful. Magnetic monopoles have not been found in space, ores, meteorites, lunar soil, or in experiments at the Large Hadron Collider. Nowhere. The abstract models of the magnetic monopole of Dirac and Hooft-Polyakov have remained abstract. They do not exist in nature. Meanwhile, magnetic monopoles and charges happily exist and are so close that there is no need to look for them. To do this, it is enough to just look at other charges. A charge is a physical object that creates a force field and interacts with other charges of the same physical nature. An electric charge is located in the numerator of the formula for the force of interaction of electric charges. A gravitational charge is located in the numerator of the formula for the force of gravitational interaction. There is no need to invent where the magnetic charge is located. Like the electric and gravitational charges, it is located in the numerator of the formula for the force of magnetic interaction. Thus, the magnetic charge is equal to Idl. It is this value that creates a force (magnetic) field. It is this value that interacts with other similar values. Therefore, it is this value that, according to the definition given above, is the magnetic charge. The magnetic monopoles found have nothing in common with the Dirac and Hooft-Polyakov monopoles. And this is good. Because the Dirac and Hooft-Polyakov monopoles do not exist in nature. And the monopoles found exist wherever there are moving electric charges, i.e. practically everywhere.
