interesting, i always through mag mines were magnetic themselves, so they would pull towards anything large and metallic. If the ships get magnetized that much themselves, wouldn't sailors wearing any metal (like belt buckles) be constantly be pulled towards the nearest floor or wall?<br>Too bad they don't have naval minesweepers like army minesweepers (just a huge rolling log of metal/chains attached in front of a tank so it just rolls through and every mine it runs into gets detonated by the mine roller which just pops up a bit from the explosion then smashes back down to continue triggering other mines). But i suppose nature of fluid dynamics and all, an underwater mine can probably do damage to a much larger area as it turns the water itself into a weapon from compression shockwaves
