The earth's north pole acts like a south pole to the magnet as it attracts the north pole of a magnet (The earth's north pole attracts the north pole of a magnet). This means that the needle of a compass is always the north pole. So, the needle will point to the south pole of the other magnet. In simple words, the North pole of the earth is actually the south pole for a magnet.

The needle should point towards South pole because the Earth's North Pole is actually the South pole of a bar magnet. Compass needle always points to the geographical North pole.
