Device for attracting submarines and the like

Submarines were a new menace during World War I, but Louis Schramm figured he had a way to defeat them. His invention (Patent No. 1,143,233) involved powerful electromagnets that would pull submarines to the sides of a ship where they could be electrified, killing their crew.

Critics pointed out that the magnets would attract anything metallic to the side of the ship, including mines.

I'm sorry, but I'm just so sick of idiots thinking magnets will pull things from far away. You see it in movies and tv shows all the time that someone commits murder by 'pointing' a magnet through a wall to pull a knife/barbell/desk into their victim.

Look at food processing -- powerful magnets just inches above the production line, and stuff still sometimes gets through.

How about we outfit a barge with a bunch of electromagnets, tow it over the Titanic, and lift it without all the submersibles collecting tiny bits and pieces!

How about we built an unmanned star of electromagnets and used it to detonate sea mines, just like this starlike device invented by an Indian person with wooden poles and ringette pucks that is used to detonate land mines?

Yudith, thanks for that link. To pick a nit, the inventor is an Afghan.
