MONEY MAGNETISM

Apparently, if you have a REALLY strong magnet, it will attract paper money. Found via News & Notes from the Society of PAper Money Collectors (Volume VIII, Number 42, April 4, 2023). -Editor

  Magnetic ink on U.S. paper money

Today's topic is money.

It buys us goods and services, but there is a little, scientific secret that the bills in your wallet hold.

So what is the secret?

That paper money is magnetic!

You need a powerful magnet, like a rare earth magnet. It is also called a neodymium magnet.

That strong magnet shows that paper money contains something magnetic.

If you remember in the past, we did an experiment in the past showing how your cereal may be magnetic. Well, the same is true with money that "don't jingle jingle, but folds."

The ink is where we find the metal!

There are green ink and color-changing inks on our currency, and some of the inks contain iron.

That is the secret to moolah being magnetic.

Apparently it's true, although us usual the laws of physics would doom Doofenshmirtz's plan in real life. Here's a paper from the University of Waterloo, where researchers had their own mishaps - "Unfortunately, the small magnet broke and everything in the nearby vicinity was soaked in the deep brown ferrofluid." -Editor
