<p>[QUOTE=&quot;Conder101, post: 286571, member: 66&quot;]Cupronickel or copper-nickel is an alloy of copper and nickel.&nbsp; As Jerome says a great many of the non-silver canadian coins&nbsp; are either pure nickel which is strongly magnetic, or the recent one being nickel plated steel which is also magnetic (The Canadian five cent pieces from 1982 to 92 are cupronickel.).&nbsp; Nickel though when alloyed with as little as 10% loses it&#039;s magnetic properties.&nbsp; Under a very strong magnetic field there may still be a slight reaction.&nbsp; (Oddly enough, aluminum also reacts if you have a strong enough magnetic field as well.&nbsp; Although for aluminum it is repelled by the magnetic field.)[/QUOTE]</p><p><br /></p>
