Abstract
An electromagnetic induction generator for use in a tubular, such as a tubular deployed in a subterranean well during wellbore construction operations, for generating electric current through electromagnetic induction. The electromagnetic induction generator has at least one conductive coil and at least one Halbach array of magnets. One or both of the at least one conductive coil and the at least one Halbach array of magnets is rotated relative to the other to increase the electric current generated. One or more gears may be provided to multiply the generated electric current.
