Physics and science and magnets OH MY! Follow me on Instagram! https://www.instagram.com/p/BhcjBtBAWl7 Today's #SlowMoScience: repelling coins! Specifically, American money. This won't work for many currencies of other countries. When a magnet is moved over a coin, the coin slides away in the same direction. This isn't from being attracted to the magnet, but because it's being repelled! Simply put, this is an example of an Eddy current. As the magnet passes over, the coin generates an electromagnetic field in the opposite direction, thus pushing against the field of the magnet! This demonstration is similar to dropping a magnet down a copper pipe (see one of my earlier IG posts). American coins are made of three different metals: pennies, zinc and copper; quarters, nickels, and dimes, copper and nickel. All of these metals are conductors of varying strengths. However, there's one property of coins and magnets that deviates from the effect seen here. More information will be in the YouTube video I'm uploading TONIGHT at Experience Daliona Science. ¬ ¬ ¬ ¬ Follow me for more #science experiments, #slowmotion demos, and new videos where I bring science to the public!
