Why are submarines demagnetized?
4,000 Amps is a ridiculous amount of current. Though when you have a nuclear power plant nearby...Also, this line made me shudder:> "...stringing an electric cable the length of the ship and pulsing 2,000 amps through the cable."EDIT: Okay maybe not that ridiculous, apparently the Luxor hotel has higher-amp lightbulbs http://www.wolframalpha.com/input/?i=4000+amps
