1. The problem statement, all variables and given/known data Bill knows that a solution with an ionic salt dissolved in itwill allow a current to flow. Bill finds this quite interesting, so he finds a piece of plastic tubing and hangs it from an apparatus. He pours seawater into the tube until it is full. He then moves a magnet around the tube. Bill then uses a cell to create a current in the solution. Will a force act on the tube? Explain your answer. 2. Relevant equations F = BIL 3. The attempt at a solution I have no idea. I'm not sure if F = BIL only applies to electron flow, or ion flow as well.
