Ufo detector

Just read an interesting and funny article in Fortean Times about the quest for UFO, or how it is called now UAP, contacts.

This little device was sold for £9 and comprised a magnetic compass needle, a battery and a buzzer. The assumed electromagnetic field of an UFO would cause a deflection of the needle that closed an electric circuit and activated the buzzer. If this device really worked is unknown

Yes, I have seen various versions of this principle applied and marketed as a "UFO detector". Basically they all fall into the same or similar type of operation, where ambient magnetic field strength is monitored, and any variation trips an alarm to say something unusual has occurred - or that perhaps a UFO is in the vicinity - or a large bar magnet has flown by. Some electronic versions I have seen use amplified environmental hum pickup from a solenoid as the base measurement, and others use a more sophisticated method of measuring the actual static magnetic field strength - like a crude magnetometer.

I was in correspondence with a scientist who did monitoring of UFO activity in remote desert regions of the USA. His monitoring method involved electrostatic field measurement (which I would agree is much more suitable than magnetic based methods). He obtained recordings of strange audio based signals that always coincided with airborne based craft activity. I have attached a short segment of his personal research diary, and the received signal example he is explaining. The quality of this recording is very poor, as it has been transcribed from his cassette tape.

Thanks for your most valuable comment Jeff. I love the image of a flying by bar magnet!😄

Your comments are raising the question if there are any structured investigations about the physical anomalies occurring if a UFO encounter is taking place. Is it a magnetic anomaly, a static electrical one, do car engines stop working, is gravity changing, is the flow of time affected?

I will read the documentation you provided.
