It is unknown whether humans can sense magnetic fields. [74] The ethmoid bone in the nose contains magnetic materials. [75] Magnetosensitive cryptochrome 2 (cry2) is present in the human retina. [76] Human alpha brain waves are affected by magnetic fields, but it is not known whether behaviour is affected. [74] [76]

In scientific tests, only about 10% of people could detect a field intensity in the range of 2-5 kV/m. [22] Such voltage differences can also create electric sparks, similar to a discharge of static electricity when nearly touching a grounded object. When receiving such a shock at 5 kV/m, it was reported as painful by only 7% of test ...
Maybe you have this superpower, too.
The latest notes were picked up by NASA's Magnetospheric Multiscale satellites, launched in 2015 to explore the Earth and sun's magnetic fields. The new research was published Wednesday in the journal Nature. Chorus waves have also been spotted near other planets including Jupiter and Saturn.
Many of the people who can adhere objects to their body can do so not only with metal but also other materials. That would suggest that the phenomenon cannot be explained by magnetism and uses a different kind of physical effect. Skeptic Benjamin Radford has used a compass to check the magnetic field of a person that claimed to be a human ...
Magnetometers can be used as metal detectors: they can detect only magnetic metals, but can detect such metals at a much greater distance than conventional metal detectors, which rely on conductivity. Magnetometers are capable of detecting large objects, such as cars, at over 10 metres (33 ft), while a conventional metal detector's range is ...
After removal of the magnetizing field, the nanoparticles decay from a ferromagnetic state to a paramagnetic state, with a time constant that depends upon the particle size and whether they are bound to an external surface. Measurement of the decaying magnetic field by SQUID sensors is used to detect and localize the nanoparticles.
