Some people can sense the Earth’s magnetic field

It is well known that many animals have the ability to sense the Earth's magnetic field. This phenomenon is known as magnetoreception.

But what about people? In a recent study, scientists at the California Institute of Technology conducted an experiment where they measured how the alpha waves of a human brain interact with a trace element that they think magnetism records. For this experiment, a Faraday cage (a device for shielding objects from external electromagnetic fields) was built. Coils that generated a magnetic field were installed in it, but with built-in switches. That is, these coils could at any moment imperceptibly switch to the "fictitious mode of operation" without creating a magnetic field.

According to scientists, during the experiment in the cell room, where there were volunteers with connected sensors of brain activity (EEG), it was absolutely dark and quiet. At the moment the coils were turned on and the magnetic field appeared, the researchers recorded pulses in the participants' brains.

Bottom line: it was found that the human brain captures and selectively processes pulses from magnetic field receptors. It should be noted that in magnetoreceptive animals this ability is much more developed, therefore they can lay routes during migration, feel approaching earthquakes, volcanic eruptions and other natural disasters.

Based on the results, scientists hypothesized that humans developed magnetoreception in the same way animals did: through constant use. The limits of our ability to use this ability have yet to be determined.
