hi,i want to know how can demagnetize a submarine?anybody can help me?
Hi,
I got it from wiki. Its called the Deperming process. It says that very heavy copper cables are wrapped around the structure and current as high as 4000 amps are injected to the cables therefore resetting the magnetic levels as suited to the environment. The process needs to be repeated again over time to maintain desired effect. Very interesting information..
