If you follow me on Instagram, I post these science demonstrations every day with multiple angles and examples!! https://www.instagram.com/p/BhSQSyGhW5P Today's #SlowMoScience is its own form of slow-motion: the Eddy current! This one is sure to warp your perception of the world. We all know the effect due to gravity makes things fall with increasing speed...unless you're a magnet traveling through a copper pipe. Or any significantly conductive, non-ferromagnetic pipe, for that matter, among whose ranks silver and gold stand (with copper right in between). Copper isn't magnetic. Slap a magnet on that bad boy and it falls right off. But drop a magnet THROUGH the pipe? The magnet...falls...really...really...slow. This is because a moving magnetic field through a conductive pipe forms an Eddy current: an electric field that opposes the magnetic field, pushing UP on the magnet as it drops (but can't quite beat gravity). ¬ ¬ ¬ ¬ Follow me for more #science experiments, #slowmotion demos, and new videos where I bring science to the public! Be sure to follow me on Twitter @thescalex, and on YouTube at #ExperienceDalionaScience! New video every Wednesday!
