In this 14-minute video, physics education researcher Derek Muller climbs inside a modified Faraday cage to let scientists at CalTech measure his ability to detect rotations of geomagnetic fields. The team of scientists had found in previous research that some human brains can pick up on these rotations when they are placed in environments with very little visual or auditory stimuli. Magnetoreception is a well-documented sensory ability among bacteria, protozoans, bees, turtles, homing pigeons, salmon, rats, whales, and cats. The CalTech research team has discovered that humans can also pick up magnetic field rotations, as evidenced "by drops in alpha wave power" following a change in field direction. We humans seem to have lost much of our capability to sense magnetic field, but remnants of this sensory ability are still detectable.
