Understanding Ultrasonic Heterodyning: EM Voltages and Human Hearing Explained

[QUOTE="beatfrequency, post: 4519302, member: 489413"] Thanks for the excellent reply. I have another tough question. I saw a demonstration that I cannot explain how it was accomplished. Maybe someone has an idea. I saw a compass with nothing around it for 20 or more feet. The compass needle oscillated between magnetic north and 90 degrees from its resting state, magnetic north, at about 1/3 of a hertz indefinitely but another compass 10 feet away did not. ELF waves are not directional so I thought somehow higher frequencies which are directional could be heterdyned into a localized magnetic field to make a directional ELF EM spotlight per say. The scientist or magician claimed he could do this on a much larger scale and turn the Earth into an NMR and ESR machine under its own magnetic field but this device helped with the signal to noise ratio. He did not explain how he projected directional ELF waves at a distance. Any ideas? [/QUOTE]
