The invention relates to an apparatus for levitation of an amount of conductive material, comprising a coil for keeping the material in levitation using a varying electric current in the coil. According 10 the invention, the apparatus comprises two coils, a first coil and a second coil, both coils generating an alternating electromagnetic field during use, the alternating electric field of the first and the second coil counteracting each other, wherein the first and second coil are positioned such that the conductive material that is kept in levitation between the first coil and the second coil is evaporated. The invention also relates to a method for generating an amount of levitated conductive material. |
