摘要: The invention is concerned with electromagnetic exploration of the earth's surface. In a method proposed by invention, primary coil powered to generate field and applied earth receiver, used detect secondary generated in response field, moved over surface earth. According Helmholtz coils ( 14.1, 14.2 ) are arranged predetermined array such manner that they generate, volume accommodating magnetic which serves at least partially null also provides apparatus for carrying out method.
