I just recently picked up some 8 pound resistence magnets and realised they easily attach themselves to Canadian quarters but not American. Does any one know why this is?

Canadian quarters are mostly nickel, which is magnetic. American quarters have non-metallic metals in them, silver and copper I think. Most Canadian coins are magnetic, except for the Penny, actual silver dollars, and the centre of the tooney (the outside rim is magnetic, the centre gold part isn't, how weird is that?).

US coins (dime, quarter, and half-dollar) have a composition of 8.3% nickel and 91.7% copper. Nickels have a higher content of nickel at 25%.
Actual silver hasn't been used in many years. Cheers!

Canadian coins are magnetic so they can be readily differentiated from American coinage by vending machines
