OVERVIEW OF MAGNETIC FIELD EFFECTS ON HUMANS

1. As a result of research (and ignoring man-made air-objects which are frequently mis-reported as UAP and other natural though exceptional meteorological phenomena, such as cloud formations), there appears to be four types of electrical charge-related formations that can occur in the atmosphere, covered in the Working Papers Nos. 1,2,10,19 & 21:

## INTRODUCTION

- Ball Lightning

- Ionospheric Plasmas

- Earthlights

- Electrically-charged Aerosols.

It is known that visible and invisible fields can be sensed when close to a UAP. In the absence of any other postulations it is assumed that the fields are electromagnetic or magnetic (or both) in nature. Further away from the object only the emissions in the visible part of the electromagnetic spectrum are sensed; as is frequently the case by human observers, photographic film and video camera detectors. The results summarised are those of medical experiments in which the intention was to study the human brain response to external fields, particularly in the area of epilepsy. There is no UAP connection given in the scientific papers. The connection is made here, because of the apparent relevance to this study.

2. The fields investigated for medical purposes in Canada have some common characteristics, and the scenario which, in

'close encounters', reportedly produces alien' and similar descriptions, may be the result of the close proximity of one or more of these field types. The difficulty is that little, if any, instrumentation is available when these phenomena occur hence suppositions rely on theory with few actual measurements on which to base firm evidence. It is clear that, while some screening from field effects can occur when a witness is in a vehicle, this may not be completely effective. Further, electrical/electronic equipment failure or poor performance or partial failure is often reported at the time, both in vehicle equipment, such as radios including Police radios - and even ignition failure. For the radios, one theory is that a strong (magnetic) field off-tunes resonant circuits in radios which use ferrite-rod type antennas. Since radio components are normally in a metal box, the implication is that the field couples with the antenna, causing a larger than normal current to flow in the antenna and into the front-end receiver coils, mounted on the ferrite rod.

3. Using the near-field ranges, calculated at Working Paper No. 2, and the example magnetic field levels used to cause temporal lobe effects, it is possible to calculate the minimum energy level which must be at the source. Further, those reports where electrical equipment has been reported as unstable (noisy) or even unworkable until the UAP moved away, have always been scenarios where the UAP has been very close - even overhead. Assuming a free-space magnetic field attenuation, proportional to $ 1 / \mathrm{R}^{2} $ and a signal level (at the observer's position) of 1mG, then, for the ranges shown, the source power is calculated, below:
