Abstract
Aspects of the invention include arranging two cylindrical magnets with transverse magnetization to be parallel to each other along their longitudinal axis. The two cylindrical magnets have a space between them and are prevented from moving relative to one another. An exemplary method includes disposing a diamagnetic object to levitate above the space between the two cylindrical magnets. A motion detector is arranged to identify relative movement between the two cylindrical magnets and the object, and an infrasound wave is identified based on the relative movement.
