The Experiment Research of the Sea-Floor Transient Magnetic Dipole-Dipole Electromagnetic System

The magnetic dipole-dipole configuration adopted in sea-floor detection is effectual. A mass of experiments in lab and field are performed in order to analyze the profile characteristic. When the exploration depth and dipolar distance are changed, the form and polarity of the profile are different. The detection result is distinct when the dipolar distance is small. But its peak value is negative. The peak value will change to positive value when the dipolar distance is increased. But the distance can´t be increase unbounded. The configuration parameters are chosen by experiment on the land. The exploration result in the sea floor are exact in this equipment
