英文摘要	In the traditional exploration electromagnetic theory, the rock permeability is usually regard as the air permeability approximately. As a result, the electromagnetic field response can be derived simply. However, study on electromagnetic response considering rock permeability is required for fine electromagnetic detection of magnetic ore bodies. In this paper, electromagnetic field response expressions of the magnetic layered earth is deduced at first, then the response curves of several kinds of typical magnetic medium geological sections are calculated. The research results show that electromagnetic sounding curves are heavily affected by the rock permeability layer when the earth is covered by a magnetic layer with rock permeability mu(r)>1.2. While as H-type and A-type curves are heavily affected by rock permeability (mu(r)>1.2) for the middle layer. On the other hand, when the magnetic layer is buried as the basement, electromagnetic sounding curves are slightly affected by the rock permeability layer.
