In some examples, a system can include an electronic device and a cooling system that transfers heat among other components of the system. The cooling system can include a pipe that contains a fluid, for example. In some examples, the cooling system can further include a magnetic piston, one or more electromagnetic coils, and a power supply. The electromagnetic coils and power supply can generate a magnetic field that moves the piston to cause the fluid to circulate in the fluid pipe. In some examples, the cooling system can further include a magnet and one or more pairs of electrodes coupled to a power supply. The magnet, electrodes, and power supply can generate a Lorentz force that causes a conductive fluid to circulate in the fluid pipe.

A method to operate an apparatus for feeding liquid metal to an evaporator device in a vacuum chamber, wherein the feed tube runs from a container adapted to contain a liquid metal to the evaporator device and wherein an electromagnetic pump is provided in the feed tube and a valve in the feed tube between the electromagnetic pump and the evaporator device. An at least partially gas permeable electromagnetic pump, which is enclosed in a pressure controlled enclosure, is used in the method wherein electromagnetic pump and the pressure controlled enclosure are controlled such that filling and draining of the evaporator device and feed tube can be done without affecting the vacuum pressure in the vacuum chamber.
