Various researchers have proposed the use of electrodynamic tethers for power generation and capture from interplanetary transfers. In this paper, the effect of tether forces on periodic orbits in the Jupiter-Io system is investigated. A series of simplifications to the Lorentz force-perturbed circular-restricted three-body problem allows the development of a conservative formulation that admits a Jacobi integral. Although the conservative approximation introduces a modest magnitude error in the regions of interest, the correct perturbation direction is preserved. The presence of the Jacobi integral is amenable to the search for equilibria, periodic orbits, and the use of dynamic tools such as zero-velocity curves. The perturbed equations of motion lead to modified equilibrium positions, which are found at both Io and Metis. New families of modified Lyapunov orbits are generated at Io as functions of tether size and Jacobi integral from preexisting families as well as the new modified equilibrium points. Stability analyses are used to evaluate the dynamical properties of tether-modified orbits, and several stable orbits are identified. Multiple new families are archived with unique dynamical properties, including orbits with multiple loops and orbits that directly lead the moon.
