Distribution of the induction of a quasi-stationary magnetic field created in a ferromagnet by an attachable electromagnet

“…Calculations that were based on the concept of an AEM-ferromagnetic specimen magnetic circuit were also carried out for a stationary case [16][17][18]. Theoretical approaches with consideration for Maxwell's equations ensure the calculation of the distribution of a stationary magnetic field, which is created by electromagnets of different configurations in a ferromagnetic system for several simple particular cases [19][20][21][22]. The results of numerical calculations of the induction of a stationary magnetic field that is created by a U shaped or solenoidal AEM in a ferromagnetic specimen are also known [23,24].…”
