Answer 2

I don't know about b part but I know about a part. The answer is magnets are sometimes used for underwater recovery. Boaters and fisherman may use a magnet retrieval tool to recover some lost items such as keys or magnetic fishing gear that have been dropped in the water. However, one concern is that the magnets will begin to corrode, especially if they are made of materials like neodymium. On the other hand, water has shown diamagnetic properties.
