Recently someone at a party told me thieves could detect a laptop in the car boot, even when turned off. At first I thought this was ridiculous, but I found some google queries provided a theory, the thieves used an inductive amplifier to detect the wires inside of a laptop.
I'm still a bit sceptical. Isn't the car full of wires anyway? Wouldn't the car's hull hide the laptop from the inductive amplifier?
