Device for ionization of a fluid

A device for ionization of a fluid, wherein the device comprises a container and a first pair of electrodes arranged in the container opposite each other and at a distance from each other, wherein each one of the electrodes in the first pair has an elongated shape with a pointy end and wherein the electrodes are arranged so that the pointy ends face each other, wherein the container is adapted for conveying the fluid in a gaseous state in a fluid flow past the first pair of electrodes, wherein the device further comprises a power supply adapted to charge the first pair of electrodes so that electric discharges take place from the electrodes for the ionization of the fluid, wherein the device further comprises a magnetic field generating arrangement comprising of a plurality of magnets circumferentially spaced around the container by a support structure, which is adapted for generating a magnetic field in the vicinity of the first pair of electrodes for affecting the discharges for supporting the ionization of the fluid.
