1. An alternating magnetic field (AMF) system (100) for producing nanobubbles comprising a pipe (110) with an enclosed core (120) mounted within the pipe, the core (120) extends along a length of the pipe (11) while allowing a liquid to flow through the pipe (110) and around the core (120) without entering the core (120), wherein a plurality of magnets (130) is housed in the core (120) oriented north end-to-north end and south end-to-south end, the magnets (130) expose the liquid to an alternating magnetic field, wherein the core (120) is shaped such that the liquid flows straight through the pipe (110), wherein a ratio of an outer diameter of the enclosed core (120) and an inner diameter of the pipe (110) is 1:3 to 35:64.
