<p>[QUOTE=&quot;desertgem, post: 1876912, member: 15199&quot;]War nickels have as you said 35% silver and 56% copper, and 9% manganese. Silver has a diamagnetic value of -2.6 , and copper -1.0 ( the minus means more repelling), however, manganese is paramagnetic ( attracting ), so they basically cancel out and would be diamagnetically about the level of water ( couldn&#039;t be observed with the slide theory). So they would not move the magnet if it was made to slide across the coin. Unfortunately, a magnet is also used to detect ferromagnetic material such as steel, and others which may be plated with silver or gold. Thus if you ask someone , did you do the magnet test, they may say yes and it didn&#039;t stick/attract it , meaning no iron or non-sliver or gold in it.[/QUOTE]</p><p><br /></p>
