Copper-plated coins are attracted to magnets because of the iron content of the steel core, whereas bronze coins are not magnetic.
Are coins magnetic?
Since 1992, coins have been made with steel, which is magnetic. (Pre-1992 coins are made out of bronze, which will not attract.) The stronger your magnet, the more coins you will be able to dangle.
What happens when you wrap a magnet in copper?
If you drop strong magnets onto a plate of copper, something remarkable happens: the magnets will slow down before hitting the surface, appearing to levitate slightly, like the copper is another magnetic force pushing them away.
Are coins not magnetic?
While nickel is also magnetic, there isn’t enough nickel in standard United States coins to make them magnetic. Even the five-cent coin, widely called a “nickel,” is only 25% nickel, with the balance made from copper. Therefore, U.S. five-cent coins don’t stick to magnets despite their nickel composition.
Is it possible to get copper to be magnetic?
So the short answer is “No, copper isn’t magnetic.” This can quickly be tested by trying to pick up a penny with a magnet. But copper will interact with magnets in fascinating ways.

Are there any US coins attracted to a magnet?
“Are any US coins attracted to a magnet?” World coins that are considered magnetic are generally made of steel or nickel alloys. In the United States, apart from the 1943 Steel Cent, we’ve never used steel for a circulating coin.
Can a magnet pick up a copper rod?
Copper is not a ferromagnetic material. That means that a magnet will not attract or pickup up a copper rod no matter which end of the magnet is used. There are magnetic materials made of alloys that include copper such as copper-nicker alloys which respond to magnetism if there is enough nickel in the alloy.
Which is more magnetic, copper or aluminum?
Aluminum is works almost as well as copper (and is much cheaper). Magnetism and electricity are closely related. When a magnet moves near copper (or other metals) it sets up electrical eddy currents. The eddy currents will repel the magnet as it falls down the copper tube. This repulsion pushes against the magnet and slows it down.
