Abstract: A hydromagnetic joint includes a first joint part having a first magnetic element with a magnetically charged surface, and a first buoyant element coupled with the first magnetic element, and a second joint part including a second magnetic element having a second magnetically charged surface that opposes the first magnetically charged surface of the first magnetic element, and a second buoyant element coupled with the second magnetic element. The hydromagnetic joint has a liquid disposed between the first and second joint parts. The first and second joint parts are moveable relative to one another and are in fluid communication with the liquid. The first and second magnetically charged surfaces have a common polarity and repel one another.
