Abstract: A fluid activating apparatus is provided. The apparatus is capable of changing a bonding structure of a fluid or allowing the fluid to be readily reacted by applying a strong magnetic field to the fluid, such as water or liquid fuel.

Abstract: Disclosed is a fluid activating apparatus having a case unit including a first body which has a hollow cylindrical structure with open both ends, and which has an accommodation space for providing a flow channel for passage of fluid, and which has first coupling portions formed at one end and the other end thereof, a second body which is arranged to cover an outer surface of the first body and which has a separation space spaced apart from a portion of the outer surface of the first body by a predetermined gap, and a first cap and a second cap which are coupled to the respective first coupling portions, and each of which has a fluid inlet port and a fluid outlet port; a magnetic force generating unit which is arranged in the accommodation space of the case unit such that the magnetic force generating unit has a central axis that is the same as that of the first body and has a diameter smaller than that of the first body, wherein the magnetic force generating unit is arranged along the flow path of the fluid s
