About 41,000 years ago, the Earth's magnetic field briefly flipped, reversing the polarity of the poles. During this time, the magnetic field weakened, becoming just 5% of its normal strength and allowing more cosmic rays to reach the atmosphere. Researchers have used data from ESA's Swarm mission to create a sound visualization of this event, transforming familiar sounds as a way to perceive the changing magnetic field around the Earth.
