Some applications of harmonic functions

Abstract

In this paper, we introduce the most important applications of harmonic functions, and the most important related to harmonic functions. We have studied the Dirichlet problem related to harmonic functions. We also studied the most important applications of the Laplace field, including the development of the magnetic phase and temperatures, we obtained results that are more accurate, including the use of Laplace field reduces noise as well as the use of the harmonic functions in measuring magnetic susceptibility leads to the correction of the contact shift.
