These errors of the modern theory of electricity are connected with the fact that only now physical science, and first of all, quantum physics, began to clarify the nature of the charges of electrons and positrons.
It turned out that there are no specific electric charges in nature, because an electron - by 2/3 of its volume - is a magnetic dipole of the north pole, called a minus, and a positron is a magnetic dipole of the south pole, called a plus. Each charge generates 1/3 of the volume of the magnetic induction of the opposite pole.
Moreover, a larger magnetic charge is considered an electric charge, and a smaller magnetic charge is considered to be the magnetic component of the charges, which, when current flows in the conductor, generates speraloid lines of magnetic induction.
