yes, one end of the battery attracts one end of the needle/repels the other while the opposite is true for the other end.

yes, I understand any piece of metal is attracted to a magnet, but that would not explain why opposite end of the compass needle are attracted to opposite ends of the battery right?

only moving charges create a magnetic field!

So your suggestion is that since this battery has at some point been connected to a circuit, that current aligned the (what are they called, territories?)in the metal and thus magnetized the casing? If this is true, would i not expect to see this from a brand new battery?

Homework Statement I'm an introductory electromagnetism course and in lab we were observing how an electric current could deflect a compass needle. however, i also noticed that the batter itself (with no wire attached, so no current) could also deflect the needle. (for ex, if you brought the...
