Re: Questions about magnets.
You can make an electromagnet with some sort of magnetically attractable metal core and a coil of wire plus an electric current to boot. They're usually weaker though. For some really strong magnets, look in any bad trashed audio speaker (not internal to a TV set).

Oh yeah, they do have N&S poles as others have mentioned, when split in two they indeed make two separate magnets. There is no such thing as the strongest pole and the best shielding is space or some seriously magnetic resistant material. I could not name one for you though.
