The theoretical limit of the magnetic field is 1042 gauss
Contrary to what was believed, recent estimates have concluded that the maximum intensity that a magnetic field can reach is 1042 gauss. Prior to these calculations it was admitted that a magnetic field could reach intensities of up to 1051 G.
To locate the gauss unit, it should be noted that the intensity of the Earth's magnetic field does not reach a gauss. Some cosmic objects, such as black holes, white dwarfs, or starry neutrons, have magnetic fields of 1017 G. From there, it is difficult to say.
Two Russian theoretical physicists have managed to pull the new limit from the Bethe-Salpeter equation. To do this, they have represented the atom of Positronium, formed by an electron and a positron, in a magnetic field of great intensity. As the intensity of the field increases, they have realized that from the limit of 1042 G, the pull force between the electron and the positron is so large that the Positronium atom itself collapses. That is, from that limit, the Positronium becomes empty.
