FIELD: mining. ^ SUBSTANCE: probe comprises generator coil, near and far receiving coils located from the generator one at the distances z1 and z2, accordingly, and having magnetic torques M1 and M2, accordingly, so that Near and far receiving coils have identical number n of turns and arranged with diameters D1 and D2, accordingly, besides Length of winding of far receiving coil is identified by ratio where L is inductance (in microhenry) of near receiving coil. Near and far receiving coils are wound by wires with diameters d1 and d2, accordingly, besides ^ EFFECT: increased accuracy of measurements due to equality of impedances of receiving probe coils. |
