Abstract: The present invention relates to a moving dipole source electromagnetic induction device and method for carrying out geophysical surveys. The device is useful to locate deeper sub-surface bodies under poor electrical conducting surfaces and for mapping sub-surfacial conductivity changes due to salinity or pollution. The device includes a transmitter coil forming a series resonant circuit with tuning capacitor producing primary electromagnetic field and a receiver set. The receiver set up picks up resultant time varying feeble secondary electromagnetic field produced by transmitter components and a target. The secondary field amplitude is improved by increasing power of the transmitter coil. The transmitter and receiver set up produces an analog signal which is fed to A/D converter to obtain a digital signal to display the obtained data on an LCD display and storing the same data in a digital computer.
