I have a one Troy ounce silver coin, and a copper coin. Both of these show magnetic drag when I move my large neodymium magnet near them. I also have a large chunk of bismuth, but when I run my magnet near it it creates no drag, but does repell a much smaller magnet tied to a thread.
My question is regarding the purity of my bismuth. Is bismuth supposed to exhibit magnetic drag, like copper, and silver?
