Magnetic Anomalies At Supposedly Haunted Locations

 The United States Geological Service has supposedly detected extremely high magnetic fields emanating from haunted locations. This could very well explain many things that people see, hear, and sense from these such locations. Unfortunately, there is still a mystery about these locations, and that has to do with the supposed fact that they are locations of increased magnetic field. I first heard about this while watching the show called Ghost Adventures: Aftershocks. On that show, they were interviewing about a scientist who was actually a parapsychologist, who was skeptical about paranormal activity. He tried to explain to the crew that the things people sense in a paranormal location are not meant to be interpreted as communication with unseen entities; instead, they are perceptions. The strongest magnetic field that he reported about (that he had ever experienced) was that in the Oman House in Los Angeles, which was once the house involved with the Manson Murders. He still couldn't explain what the supposed entities were that he witnessed. Even though I'm not necessarily an admirer of ghost investigations (in particular, Ghost Adventures), the fact that they had a skeptic who was also a parapsychologist tell his side of the explanation, I think that provided the episode with great insight from a scientific perspective! Don't get me wrong, paranormal explanations are really fascinating, I think that scientific explanations are also just about as intriguing. I think that there is much that we have yet to learn about this world in general, and maybe it goes beyond just the paranormal. I was compelled to search for links that could verify the claims about such magnetic anomalies, and here is what I found: http://www.critical-thinking.org.uk/paranormal/magnetic-anomalies-and-hauntings.php
