We Sinkies talking about common magnets here, you don't come here atas atas with rare-earth magnet. You expect me to waste a few hard-disk for neodymium magnets to play?
made in china, relatively cheap. in fact for rare-earth magnets, u.s. pentagon waived the made in china requirement (bo pian) because only china has the capacity to produce them in large quantities and at lower cost. and they actively source and mine them all over the world where ever they can find them. it's a very much sought-after component in defense and medical industries, and some say space too. in future, gms' ufo will require much of rare-earth magnetic components. :p
Really hard to believe we are so cheap.....but talk big and boast so loudly all the time.
i keep both iphone and samseng away from my bart pass as they affect the magnetic properties and thus monetary balance of the card.
the university of maryland conducted magnetic experiments with several metals and produce interesting results.

the most intriguing is that a form of steel that comprises iron, nickel, carbon, and chromium becomes non-magnetic when they come together as a composite or alloy.
"It may be that the Nickel (Ni) in the nickel coin somehow disrupts the electrical currents. This seems possible since adding Nickel (Ni) to Iron, Carbon, and Chromium a form of stainless steel is created that is not magnetic even though it contains Iron. But dimes and quarters have Nickel as well, just less."

Sorry but i don't have answers
It is because of the chromium! Nevertheless, this does not negate the fact that pure nickel can be attracted by common magnets without, in your own words, "ferrous (iron) content".
yes, you're right. pure nickel is ferromagnetic.
