They are made of metal, so why are they not magnetic?

Actually almost all coins are magnetic now. Nickel, silver, gold, or copper are too expensive to make coins out of. The new pennies because of the way the coating and alloys work are magnetic too. The only coins that are nonmagnetic are older coins with high levels of nickel, copper, silver or (and bless you for asking) gold.
Get a strong magnet and check it out. It is surprising the things that are magnetic. I never would have expected diamonds to be magnetic, but it takes a rare earth magnet to pick those up.

While yes they're made of metal, but there is hardly any iron (Fe) in coins stamped today to amke them ferrous magnetic. Instead, they are made of Copper with Zinc coatings, making them useless for a magnet. This goes for coins that you would typically have in your pocket (nckel, dime, pennies, etc.)

You mean the gold liberty coin? besides, if that's a gold or silver coin, particular that makes it pretend. actually, I even have by no capacity are available in the time of an American coin it incredibly is magnetic. i be conscious of that some international places, like China, have funds that are magnetic.

Not all metals are magnetic. Look up para- and ferro-magnetism to get a better idea of how things become magnetic and which ones can stay that way.

Nickel is magnetic. Not like iron, but you can feel it. Are nickels still made of nickel? They made steel pennies to conserve copper during Word War II. There was a lead shortage, so used copper for bullets.

Iron is magnetic, and nickel is. There is not that much nickel in nickels, and pennies are copper and zinc, not magnetic. So coins are not magnetic.

Because their atoms balance out their charges.
