Metals are exposed to the atmosphere and corrosive environments such as the sweat on the palms of hands. As coins are designed to be around for a long time (unlike banknotes) the metals they are made from need to be a of very low reactivity so they do not corrode.
How can you magnetize US coins?
No. "Magnetic" means that a piece of metal is itself magnetized, so coins are never magnetic. However metals like steel and nickel are attracted to a magnet. But in the case of US coins, most of them contain a high enough concentration of other metals (copper today, silver in the past) that they're not attracted to a magnet.The only exception to this were the famous 1943 1-cent coins that were made from steel because copper was needed for the war effort.

Copper, Silver and Gold are the traditional "coinage metals". However many modern coins around the world contain nickel because it's relatively inexpensive and very resistant to wear. Low denomination coins are often made of plated steel or zinc, while brass alloys are used to give higher-denomination coins a golden appearance.

Raw materials used in coins typically include metals such as copper, nickel, zinc, and sometimes steel. These metals are combined in specific ratios to create the desired composition for the coin's value and durability. The process of minting coins involves shaping these raw materials into coin blanks, which are then stamped with designs and inscriptions before being put into circulation.
