Abstract
Method for controlling heat transfer between two objects. In one embodiment, the method includes providing a first current through a first electromagnet disposed about a container holding magnetorheological fluid to generate a first magnetic field such that particles in the magnetorheological fluid align with the first magnetic field to conductively couple a first conductive element to a second conductive element; and providing a second current through a second electromagnet disposed perpendicular to the first electromagnet to generate a second magnetic field perpendicular to the first magnetic field such that the particles in the magnetorheological fluid align with the second magnetic field to conductively uncouple the first conductive member from the second conductive member.
