Description

technical field

[0001] The invention relates to a generating and receiving system for a Debye magnetic field induced by the wake of an underwater vehicle, and belongs to the technical field of weak special magnetic field signal generation. Background technique

[0002] In 1933 Debye proposed a method to determine the mass of electrolyte ions. It is assumed that the difference in the friction coefficient of each ion induces relative motion when fluid particles are accelerated. Therefore, different charged species (such as ions) or solutions moving relative to each other generate an electromagnetic field at the same frequency as the sound source, which is the Debye effect. By measuring this electric field (or magnetic field), the coefficient of friction, and thus the ion mass, can be determined. Under the guidance of this theory, the existence of the Debye electric field was verified experimentally in 1948; in 1980, Vhvlyanskii and others carried out the experimental verific...
