If you break a magnet, do those individual pieces now have a N&S pole each?

What is the strongest pole?

What is the most effective way to shield from magnetic fields?

Where can I buy magnets besides at the hardware store?
The stronger the better (but still relatively cheap, and also lightweight).

I know some of these.

Yea, all magnets are N & S.

Yes, breaking magnet means N & S pole
