Some Humans Can Sense Earth’s Magnetic Field, Fascinating Experiment Suggests
During carefully controlled experiments, participants sat upright in the chair with their heads positioned near the center of the magnetic field, while EEG data was collected from 64 electrodes. The hour-long tests, in which the direction of the magnetic fields were rotated repeatedly, were performed in total darkness. The experiment involved 34 adult volunteers, who collectively participated in hundreds of trials; all tests were done in a double blind manner, and control groups were also included.

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.

World Magnetic Model Out-of-Cycle Release | News | National Centers for Environmental Information (NCEI)
Earth’s northern magnetic pole is moving quickly away from the Canadian Arctic toward Siberia. This movement has forced NCEI’s scientists to update the World Magnetic Model (WMM) mid-cycle.

Earth’s magnetic field is acting up and geologists don’t know why • Nature
Alexandra Witze:
<p>Something strange is going on at the top of the world. Earth’s north magnetic pole has been skittering away from Canada and towards Siberia, driven by liquid iron sloshing within the planet’s core. The magnetic pole is moving so quickly that it has forced the world’s geomagnetism experts into a rare move.

On 15 January, they are set to update the World Magnetic Model, which describes the planet’s magnetic field and underlies all modern navigation, from the systems that steer ships at sea to Google Maps on smartphones.

The most recent version of the model came out in 2015 and was supposed to last until 2020 — but the magnetic field is changing so rapidly that researchers have to fix the model now. “The error is increasing all the time,” says Arnaud Chulliat, a geomagnetist at the University of Colorado Boulder and the National Oceanic and Atmospheric Administration’s (NOAA’s) National Centers for Environmental Information.</p>


Isn't this sort of the premise of <a href="https://www.imdb.com/title/tt0298814/">the 2003 film The Core</a>, which critics noted proved that the centre of the earth is actually cheesy?

Oh, there's an update: "The release of the World Magnetic Model has been postponed to 30 January due to the ongoing US government shutdown."
