Irrelevant, since the magnetic force acting on the low mass needle is obviously well over 100 newtons. It would definitely move.
If Ellie swallowed that compass and the force on the needle was 1000 Newtons, would it lift her up and smash her against the walls? How strong of a magnetic field are we talking about that will create a force of 100 N on a compass needle? The attraction/repulsion force between two magnetic bodies is related to the strength of the magnetic field of each body. Since a compass needle has such a weak magnetic field, the other magnet would have to be extremely powerful. I'm not saying it's not possible. Afterall, the machine was pulling in the control boat. So it was a pretty strong magnet.
So wouldn't Ellie's headset have also come off since there are magnets in the speakers?
