Humans Might Be Able To Sense Earth's Magnetic Field (theguardian.com)

A new study from researchers at the California Institute of Technology suggests that humans can sense the Earth's magnetic field. "We have not as a species lost the magnetic sensory system that our ancestors [millions of years ago] had," said Prof Joseph Kirschvink, leader of the research from the California Institute of Technology. "We are part of Earth's magnetic biosphere." The Guardian reports: Writing in the journal eNeuro, Kirschvink and colleagues in the U.S. and Japan describe how they made their discovery after building a six-sided cage, the walls of which were made of aluminium to shield the setup from electromagnetic interference. These walls also contained coils through which currents were passed to produce magnetic fields of about the same strength as Earth's. Each participant was asked to enter the cage and sit still on a wooden chair in the dark, facing straight ahead towards the north. During the experiment, the team measured the participant's brain waves using an electroencephalogram (EEG).

In some experiments the applied magnetic fields were fixed in one direction, while in others they were rotated. In still others the machines were turned on but no magnetic field was produced -- meaning the participant was only exposed to Earth's natural magnetic field. The participant was unaware which experiment was under way. The results, gathered from 34 adult participants, revealed that certain scenarios triggered a drop in participants' alpha brain waves -- a change that is linked to the brain processing information. This occurred if the applied magnetic field was pointed north and then swept upwards or downwards, or directed down while pointing north and rotated anticlockwise. That is similar to a human in the northern hemisphere nodding their head, or turning their head to the right respectively.
Kirschvink said the responses showed that the brain was clocking an unexpected change in the environment. "Crucially, he said, it means that humans must be ale to detect such changes -- although the strength of the response varied hugely among participants," reports The Guardian.

The authors say the new research suggests the human system can tell north from south via a mechanism involving special cells containing iron-based crystals. "These crystals are thought to rotate rather like the needle of a compass, opening or closing pores in the cells, thereby affecting signals being sent to the brain," the report adds.

All they would do is pick the switch settings and record them outside the view of the test subject who wouldn't know when switches where changed or their positions. Another researcher would be asking the test subject the "how do you feel" questions and recording the results. This way, the research subject would never come into contact with someone who had come into contact with anyone who knew the state of the WiFi signal. Thus it's called double blind.

    Magnetic force *IS* electric force, which *IS* velocity. So yeh, we have electric flows, so of course we can detect magnetic fields.

    Literally electric is a 1F oscillation (the universes resonant frequency), all those oscillations in the electron do NOT cancel out, the motion of the electron is complex not random.
    Magnetic is an F/2 oscillation.
    Velocity is wave surfing over the 1F field, you push a component of oscillation into the direction of travel, and each resonant oscillation, its a little bit more out of phase and shoved along a bit. The same mechanism for light and for matter (which is the same).

    I'm playing with superconductivity now in sandbox simulation. If the electron (F2 donut / -ve monopole/ F2-anti-donut) travels along its edge, it has no magnetic field. All of the velocity in the spin of the donut is put into that "wave surfing" velocity of the electron. Each rotation takes it slightly out of phase and shifts along the field to stay in resonance. At any non-zero angle to the direction of velocity, the electron unpacks an F/2 oscillation, i.e. magnetic, but at zero all the spin goes into velocity.

    Heat is oscillations too. It's any oscillation that (like velocity) takes an oscillating dipole away from resonance. Can you feel heat? Yeh of course you can, so you can detect magnetism.

    ***********

    You can even prove magnetic is really electric force, because they can interact directly, not via the electron:

    1. Produce a magnetic field, with near-linear field lines along an axis.

    2. Take two superconducting plates and produce an electric field between them.

    3. Place the plates cutting one side of the field lines. The electric field and magnetic field should be in the same axis (i.e. not Flemings RHR/LHR).

    4. Superconducting plates do not have a magnetic field. So any interaction between the magnetic field and electric field between the plates must be direct, and not via induction-creates-counter-magnetic-field.

    5. At this point the plate will be a 1F oscillating field, and magnetic field a F/2. Ever 2xF cycles everything cancels out. The plates will be oscillating tiny proton sized oscillations in the magnetic field.

    6. Move the plates closers together, this should be resisted by the interaction of the electric and magnetic fields, it should require force to move the plates. As you disturb the resonance, it will require force.

    7. Since there is no magnetic component from the plates, the interaction cannot be via magnetic force.

    8. Conclude magnetic and electric are the same force because they directly interact.

    9. Want more proof? Change the material in the plates to a material with a different magnetic property, the force is related to the electric field across the plates NOT the magnetic properties of the plates.

    Electric (1F electric, the kind you know as electric) DIRECTLY interacts with F/2 magnetic.

    After the experiments, none of the participants said they could tell when or if any change to the magnetic field had occurred. But for four of the 34 participants, the EEG data told a different story.

    As noted in the new study, the researchers recorded “a strong, specific human brain response” to simulated “rotations of Earth-strength magnetic fields.” Specifically, the magnetic stimulation caused a drop in the amplitude of EEG alpha waves between 8 and 13 Hertz—a response shown to be repeatable among those four participants, even months afterward. Two simple rotations of the magnetic field appeared to trigger the response—movements comparable to a person nodding their head up or down, or turning it from left to right.
