They operate a gigantic electromagnet inside it, around 1.5 to 3 teslas and sometimes as much as 7.
Brief asspull calculation of 3 teslas is about 18000 newtons of pulling power, or 1800kg. You seen those youtube videos of people playing videogames and character ragdoll on crazy physics? That's what that machine will do to you if you step up on it wearing metal.
