Difference (from prior major revision) (no other diffs)

Changed: 3,4c3,6

from the article: "are iron, some steels, and the naturally occurring mineral lodestone?" Since steel is an alloy of iron, and loadstones contain iron, shouldn't the list of natural magnets be changed to "iron, nickle, and cobalt."

from the article: "are iron, some steels, and the naturally occurring mineral lodestone?" Since steel is an alloy of iron, and loadstones contain iron, shouldn't the list of natural magnets be changed to "iron, nickle, and cobalt." Lodestone contains iron, but only in the same way that salt contains chlorine: it is the particular way it contains iron that makes it magnetic. You could change it, but they're only examples - the only importance is that everyone will know what they are.
