North Pole or South Pole

Is It North or South?

In our lives, we have a thing which is called magnet. It's a thing which has 2 poles, north and south.

As people know that if 2 poles with the same kind are close to each other, they attract each other.
In contrast, if 2 poles with different kind are close to each other, the will move and push each other.

We know that magnet is the main part of a compass...
Earth also has 2 poles, North and South.

The question is, is it the north pole of the magnet which is attracted to the north pole of earth?
Or is it the south pole which is attracted to the north pole of earth?

The answer:
It's the north pole of the compass which is attracted to the north pole of the earth. Why?
It's because that the north pole of the earth doesn't really has 'north' pole, it has south pole instead.
It was named the north pole of the earth not because of its pole, but because of its location, which is on the north side of the earth. The truth is that the north pole of the earth has south pole, and the south pole of the earth has north pole.

Have fun!^^
