Magnetic Variances Associated with ‘Haunt-type’ Experiences: A Comparison Using Time-Synchronised Baseline Measurement
Behavioural Brain Sciences Centre, School of Psychology
University of Birmingham
Excerpts:
Some animal studies have also shown that overt occurrences of limbic motor seizures increased significantly when a 7Hz amplitude-modulated magnetic field varying between 10nT to 50nT were applied for two hours duration (Michon & Persinger, 1997).
Magnetic surveys of reputedly haunted locations have suggested that both increased levels of the localized ambient GMFs and increased levels in EMFs can be associated with anomalous effects and strange experience. It has also been argued that the ambient geomagnetic field varies more over small spatial distances (e.g., in a room) than what would be expected naturally. (Nichols & Roll, 1999; Roll & Nichols, 1999; Persinger & Koren, 2001) (Roll & Persinger, 2001; Roll, Moody & Radin, 1996) (Nichols & Roll, 1998; Persinger et al., 2001; Roll, Maher & Brown, 1992)
Note the preliminary frequency analysis here revealed a small 7Hz to 8Hz field in the pillow area alone.
The study was carried out at Muncaster Castle, Ravenglass, in Cumbria, England. This location has been actively investigated exclusively by the author since 1992. It represents one of the longest running continued field investigations into a haunting ever carried out. A detailed review of case events is beyond the scope of the present article, suffice to say the following: over the course of investigation numerous eyewitnesses have been interviewed and their testimonies evaluated, many site examinations have taken place, and field-based investigations have been carried out continuously since 1992.
These values are summarized for each session and sensor in Table1.
This gives an initial indication of where and when the strongest fields and highest variances occurred. All values are given in nanoTesla (nT). Secondly, the data from both sensors for the full 4-hours was merged into one large data file. This file contained over 900,000 magnetic samples across the two sensors combined.
In the present study, over the course of the 4-hour measuring period, the total combined magnetic field measured in the window area increased more than the combined fields measured in the pillow area (25nT versus 5nT). The difference in the increase between the sensors was significant.
---> The smaller increase at Sensor A is consistent with the field distortion idea mentioned above, where amplitudes may be artificially reduced in the pillow area (or biased away from it) due to nearby fixtures and fittings in the base of the bed.
However, perhaps more interesting was when the total field was decomposed into the individual axes analysis. This revealed that the time-based variances in the magnetic fields measured in the pillow area were substantially and significantly higher than the variances measured in the window area (except for the z-axis).
The magnetic properties that characterized the two sensor locations seemed to remain relatively constant over the 4-hour measuring period. This may imply that occupants of the bed would, at least in principle, be exposed to the complex field over a more prolonged time period.
Finally, although a detailed analysis of frequency components is beyond the scope of the present article, a preliminary examination of the signals for session 1 revealed a small but continuous peak at 7Hz to 8Hz (picked up in both x and y-axes) from the pillow area.
The measurement session lasted for 4 hours of continuous time-linked monitoring. In terms of nearby electrical devices, the room is only equipped with side lighting and these were left on. There were table lamps either side of the Tapestry room bed, and two lamps situated on either side of a dressing table near the window area. With the exception of the sensors, and a ceiling mounted fire alarm, these were the only electrical devices in the room (and a similar arrangement is employed in all adjacent rooms). No individual entered the TR (Tapestry Room) during the measurement period.
---> Irrespective of the underlying mechanism it is clear that occupants of the bed are exposed to a highly spatially variant field with ambient levels around the torso area that were double that of normal levels and almost three times that of the pillow area.
-->Sensor A (pillow area) provided an overall value of 30491nT
--->whereas Sensor B (window area) produced an overall field of 77857nT
(a difference of approximately 47366nT).
