SUMMARY
A compass placed inside a bar magnet will point towards the north pole of the magnet, as the compass needle aligns with the magnetic field lines that run from the south to the north pole. This behavior is due to the compass needle's north end being attracted to the magnetic south pole of the bar magnet. Historically, the north pole of a magnet was defined by its attraction to the Earth's geographic north, which is actually a magnetic south pole. This understanding clarifies the relationship between compass direction and magnetic fields.
