Abstract
An induction resistivity tool incorporated into a downhole tool string comprises an outer wall of a downhole component having an outer surface, and at least one induction transmitter assembly disposed along the outer surface. The transmitter assembly includes at least one induction transmitter coil which is wound about one or more transmitter cores. The transmitter assembly is adapted to create electromagnetic fields that originate the induction signal from outside the outer wall while substantially preventing the induction signal from entering the outer wall.
