When we study magnetism, we learn that certain animals have awareness of magnetic fields and can use it for navigation. Certain birds are known to have magnetite in their skulls. Here's a nice update of recent findings regarding magnetoception in birds.
Humans do not seem to have this capability. But that doesn't mean our brains are entirely oblivious to magnetic fields.
Veritasium's Derek Muller dons a sensor-laden shower cap of science to test his brain's awareness of the magnetic field it's immersed in. Could it be that the brain senses magnetic fields but doesn't share the information with our consciousness? Take a look.
Can Humans Sense Magnetic Fields?
