Are dimes magnetic?
If you mean, are dimes attracted to a magnet, the answers
are No for US dimes and Yes for Canadian dimes.
American dimes are made of copper and a small amount of nickel.
While the metal nickel is in fact attracted to a magnet there's not
enough (only about 8.3%) in an American dime to show any
Canadian dimes were made of pure nickel up till the end of the
1990s, and have been made of steel since then. Both of these metals
are strongly attracted to a magnet.
