Are Coins and Pennies Magnetic? (Why?) [2021] - Simply Magnet

16-02-2021· In copper-nickel alloy, we know copper is non-magnetic. US coins contain only 25 percent nickel and 75 percent copper. That's why they are non-magnetic. Let's also talk about the US currency, i.e., penny, quarter, and dime. The quarter is 91 percent copper and 9 percent nickel, therefore it is non-magnetic.

Q: What causes iron, nickel, and cobalt to be attracted to ...

29-05-2010· They almost completely cancel each other out. However, sometimes (in iron, nickel, and cobalt for example) you'll have one or more un-paired electrons. The magnetic fields of these electrons aren't canceled out by another, oppositely-oriented, electron. As such they lend an overall magnetic field to the atom they inhabit.

Are any US coins attracted to a magnet? - Quora

Magnets attract ferrous metals— metals having a high iron content. Coins are generally made of nonferrous metals, such as copper, brass, bronze, nickel, aluminum and (mostly in the past) silver and gold. Those metals are non-magnetic. An exception is the U.S. steel pennies that were made (briefly) during World War II.
