Abstract

TEM survey under objects that containing superparamagnetic particles, the effects of magnetic viscosity can have a significant impact on the received signal. At present, such effects of magnetic viscosity are considered a nuisance, while some researchers point out that they contain useful information.The article presents a mathematical modeling of impulse response of viscous remanent magnetization. Using the lognormal particle distribution model, various impulse responses of the magnetization were modeled. The results of attempts to restore the distribution parameters and of model impulse responses are presented. An estimate of the effectiveness of the inversion of synthetic impulse responses is given.
