"Magnets can work underwater, but can they work just as well in different amounts salinity? The answer is yes, they can. Magnets use force, so they would work the same underwater as they would in the air. Other researchers found that water is diamagnetic, which means that it exerts a weak magnetic field and resists other magnetic fields. Other researchers are also creating retrieving magnets to help retrieve fallen objects like keys, tools and equipment. "
