Moronium Posted March 22, 2019 Report Share Posted March 22, 2019 (edited) Many humans are able to unconsciously detect changes in Earth-strength magnetic fields.... The experiments showed that, in some participants, alpha power began to drop from baseline levels immediately after magnetic stimulation, decreasing by as much as 60 percent over several hundred milliseconds, then recovering to baseline a few seconds after the stimulus. The tests further revealed that the brain appears to be actively processing magnetic information and rejecting signals that are not "natural." For example, when the vertical component of the magnetic field pointed steadily upward during the experiments, there were no corresponding changes in brain waves. Because the magnetic field normally points down in the Northern Hemisphere, it seems that the brain is ignoring signals that are obviously "wrong." A few comments: 1. None of this appears to be conscious, so it's nothing we "know," and yet... 2. "The brain" is controlling reception of the signals, the signals are not, in themselves, "causing" anything in the brain. This indicates that the effects are not "mechanical," but subject to selective elimination by "the brain." 3. In terms of duration, the effect is minute. 4. It's only some, not all, humans that display this infinitesimal "reception." Interesting, but seemingly not significant, as a practical matter. The reference to "Human Geomagnetic Sense" in the headline appears to be little more than clickbait.

hazelm Posted March 22, 2019 Author Report Share Posted March 22, 2019 It is over my head but I am curious to understand it for one reason. I shan't go into that unless I understand what they are saying. A magnetic field - is electricity in any way involved with a magnetic field? I'll start there. Meanwhile, dinner time!

Yes, it is, and the two are so interrelated that they are often referred to as "electro-magnetic (EM) waves." According to this guy: ...magnetism is a phenomenon that is produced as a byproduct of electricity... When electric charges begin to move, this is when magnetism takes place.The main difference between electricity and magnetism is magnetism’s presence....Simply put, electricity can exist without magnetism, but magnetism cannot exist without electricity. https://thenextgalaxy.com/difference-between-electricity-and-magnetism/ Electromagnetic waves of different frequency are called by different names since they have different sources and effects on matter. In order of increasing frequency and decreasing wavelength these are: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays. https://en.wikipedia.org/wiki/Electromagnetic_radiation Edited March 22, 2019 by Moronium hazelm 1 Quote Link to comment Share on other sites More sharing options...

According to this guy: https://thenextgalaxy.com/difference-between-electricity-and-magnetism/ https://en.wikipedia.org/wiki/Electromagnetic_radiationThank you, Moronium. I shall read those. Later: All right. something I read there makes me think I am talking about electromagnetic radiation - or maybe just magnetic radiation. Maybe not but the comment/question is this. I am assured that there is a very small magnetic field around the human body - maybe more for some than others, depending on how dry the skin is or some such. Standing there in a magnetic field, can the human body absorb a bit of that electromagnetic radiation? The connection I am making is this. What I am talking about is not static electricity because I am not walking across a carpet. I am not even on a carpet. I am in the kitchen on a tiled floor. I can place a styrofoam cup on the counter and place my fingers a short distance away from the cup. As I move my hand toward the cup, it will back away. Another: I was once visiting a friend when her husband set up his toy train on the floor. When he turned it on, it failed to move. I suspect the battery had run down. I placed two fingers on the track in front of the train and it moved. As long as I kept my fingers moving forward, the train kept following. I am wondering. Does that relate to these magnetic fields? Am I talking about magnetic radiation? Edited March 23, 2019 by hazelm Quote Link to comment Share on other sites More sharing options...
