Design of Receiving Inductive System for Equipment for Electrical Exploration of Earth's Crust

The design of a receiving sensor system as a combination of shielded collinear multiturn cylindrical coils on ferromagnetic cores for use in a task of earth exploration by TPM was discussed. The simulations of secondary field in receiving coils were made. An impact of the mutual influence of the sensors with ferromagnetic core was studied for investigation the level of a measuring error and optimal distance between elements of receiving system.
