Solution

Inorder to mark the poles, hang up the magnet by a light thread so that it hangs freely. When it comes to rest, we notice that the magnet is lying in a North-South direction. The north pole of the magnet faces North and South pole faces in South direction. Thus north pole of the magnet can be marked.
