Abstract
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.
