1. Metals that are attracted to magnets: iron, nickel, cobalt, and steel (which contains iron).
2. Metals that are not attracted to magnets: copper, aluminum, brass, and stainless steel (some types of stainless steel are magnetic, but many are not).
3. Coins that are attracted to magnets: pennies (modern pennies are mostly zinc with a copper coating, so they are not magnetic), nickels (5% copper, 95% nickel, so they are magnetic), dimes (copper-nickel alloy, magnetic), quarters (copper-nickel alloy, magnetic).
4. Conclusion: Only metals containing iron, nickel, or cobalt are attracted to magnets. Most coins are made of alloys that include these metals, so some coins may be attracted to magnets.
