The video is about how to tell real silver from fake silver using N54 Neodymium magnet.
The video is about how to tell real silver from fake silver. To do this experiment all you need is a few coins and a neodymium magnet. So what we will do is using the neodymium magnet and we will slide it down the coin. We will see what happens.
As you can see, it moves pretty slowly. Also 45 degrees angle. Ok let’s try another one, it moves a lot quicker than the previous coin. So we can tell that this one is actually fake silver. So this happens because the magnetic field induces a current in the conductor, which causes an electromagnetic braking effect to be exerted onto the magnet. And that’s why when we tried with this coin. It always moves a lot slower. Have fun and try it at home.
