The video is about a cool and fun science experiment by using a neodymium magnet and a dollar bill.
Today I am going to show you a very cool experiment using a neodymium cylinder magnet and a dollar bill. So first I will take the rare earth magnet and hold it above an area on the dollar bill where there is a lot of ink. As you can see, it’s magnetized. And we will move around with the magnet, you can also try the president’s lapel or jacket because of this a good area with a lot of ink. This is because the ink contains iron oxide or other magnetic particles, and also if you hold up here, maybe bent it a little bit, and then you can see how it attract to the magnet as well. Pretty cool right? Try it at home.
