Abstract For the purpose of obtaining the x-component apparent resistivity of fixed-loop TEM, the authors made the fixed-loop equivalent to some vertical magnetic dipoles so as to calculate the x-component TEM response. The x-component apparent resistivity of fixed-loop TEM can be obtained when channel data of every time are fitted by response of uniform halfspace, and each halfspace resistivity can be regarded as corresponding channel's apparent resistivity. The calculation results indicate that the method is effective and its precision is enough, and hence this tecnique can provide necessary basis for the comprehensive interpretation of two or three components with the fixed loop TEM method.
