magnetic fields - What's the difference between the north and the south pole on a magnet?

I was testing out objects with magnets and I didn't understand what made the north pole different from the south pole. I thought the poles were made of different materials, but I realized it wasn't. Can someone tell me what factors differentiate the north from the south?

Answer

The North pole is where field lines come out and the South Pole is where they go into the magnet. That is all there is to it.
