Electrical power may be generated at a downhole position of a production well by way of electromagnetic induction through oscillating linear translation driven by the flow of a fluid being transported by the production well. In exemplary embodiments, a conductive coil is disposed in a fixed position along a length of a production pipe such that the conductive coil encircles the production pipe. A linear translation apparatus is disposed radially inward from the conductive coil and is configured to move linearly parallel to a longitudinal axis of the production pipe and within the conducting coil by harnessing mechanical energy from fluid flowing within the production pipe. Magnets are affixed to the linear translation apparatus to cause electrical power to be generated in the conductive coil by way of electromagnetic induction responsive to the magnets passing by the conductive coil when the linear translation apparatus is in motion.
