Coulomb's law (1785)
-Style, done by two magnetic pole which is one on the other, is proportional to the strength of the mekanitisme-straight poles and comparable back with quadratic distance between the two poles.
-Style, done by two objects (which are each electrically charged) the one on the other, is comparable to the barrel with a strong electrical charge of the objects and comparable feedback with quadratic distance between the two objects.
