Claim:
1. An apparatus for controlling heat transfer between portions of a substrate comprising: a substrate including at least part of a hydraulic circuit, the hydraulic circuit comprising a plurality of microconduits, the plurality of microconduits including a first microconduit and a second microconduit; a liquid metal flowing through the hydraulic circuit; and a magnetic field source configured to provide a magnetic field to selectively direct the flow of the liquid metal between the plurality of microconduits; wherein the flow of the liquid metal through the hydraulic circuit transfers heat between a first portion of the substrate and the liquid metal; and wherein the magnetic field is activated to initiate the flow of the liquid metal in a desired direction and is inactivated after the flow is initiated such that the flow of liquid metal continues in the desired direction through the hydraulic circuit via surface tension.
