Embodiments include a receiver that has a unidirectional conductor having a closed conductive pathway that encircles a passageway for a moving projectile. The unidirectional conductor permits current to flow through it in substantially only one direction around the passageway. As the projectile and its associated magnetic field move past the unidirectional conductor, the moving magnetic field induces a current flow through the closed conductive pathway, which in turn generates a magnetic field behind the projectile having the same polarity as the projectile's field. The two fields attract one another, which both exerts a braking force on the projectile and tends to align the two fields. Alignment of these fields centers the projectile away from the passageway wall. Because the unidirectional conductor permits current to flow in substantially only the direction that produces a field having the same polarity as the moving field, the opposite-polarity repulsive magnetic field that would otherwise be generated ahead of the projectile, which would otherwise deflect the projectile from its path, is suppressed.
