The process of understanding to 'medium effect' and its verification with modeling

摘要

The "Medium Effect" this paper introduces is a physical phenomenon of magnetic field distribution contrasts caused by different media around the magnetic body and the variation of media movement status, including in air, static water, static salted water. The paper also discusses the thinking and understanding process to the phenomenon of "Medium Effect" discovered in engineering explorations and the investigation to confirm it through modeling experiments. In general teaching materials of magnetic exploration, the adjacent media surrounding magnetic body are usually considered to be background field, and without considering the media interference with the magnetic field distribution caused by magnetic body. The discovery and verification of "Medium Effect" can create some certain effects of applications, such as the study of geophysics, magnetic theory of physics, searching and position to magnetic targets under water, and magnetic survey in water areas.
