The author of the article did not encounter a single source on the Meissner-Oxenfeld effect, where the version that this effect is explained by the presence of eddy currents in superconducting ceramics would be questioned. But, in the opinion of the author of the article, ceramics in such a state are surrounded by such gravitational fields, which, when cooled, turn into gravimagnetic fields, which, together with the gravimagnetic fields of the Earth, pull all the magnetic fields from the ceramics body.

The theory of electricity formed the opinion that Coulomb forces act only between charges. Actually, between opposite charges in metal conductors there is a zero potential of the conductor. And it is precisely this zero potential that is the central element of electricity, without which no current will run anywhere because the electric potential difference between the zero potential of the conductor and the negative (or positive) potential of the current source gives rise to the force of charges in the circuit, gives rise to EMF
