I am curious about the possibility of building a large permanent magnet that could exert a huge pushing/pulling force of about 135 million Newtons. In answering the questions, I wanted to have these following points addressed:
1. The magnet is 30m wide by 30m long...would have to push a plastic container (that is 30m wide by 30m long and 20meter high) that has a steel lined bottom, down in a body of water about 15 meters. (thus displacing down a force of about 135,000,000 Newtons? Thus...how high would the magnet dimension be to achieve this push? (i.e. 30m * 30m * ?m)
2. For the first case no use of natural expensive rare magnetic elements such as Neodyium or Samirum cobalt -- just the use of permanent magnets made using regular industrial methods (such as high temperature heating etc...)
3. For the second case how thick would the magnet have to be if it was made of Neodyium or Samirium Cobalt?
