OK, so ghosts and magnetic field correlation is a well known fact. But what kind of magnetic field are we dealing with here? If it is just a simple strong fluctuating magnetic field then I can say that all high voltage AC power lines are haunted. Also I stored a bunch of Neodymium magnets in my room (waiting for virtual ghost experiment), but my apartment is definitely not haunted. Anybody knows what kind of magnitude and the pattern of the fluctuation?
Also if there is magnetic field, I expect to see electric field as well, or maybe electromagnetic waves, because they usualy comes together. Also it is usualy easier to measure electric fields rather than magnetic fields. Some devices can actually detect the electric field from human presence. So do people actually tried to measure the electric field instead of magnetic?
BTW, zygon, that was one brave experiment
