ABSTRACT:
A wellbore tool for optimizing magnetic signals is provided. The wellbore tool has a tool body and an electric current driving device with an insulated gap on the downhole tool body. The electric current driving device generates electric current across the gap. The wellbore tool has a a magnetometer capable of measuring a magnetic field.
