The discovery that a compass needle always points north is attributed to the Chinese during the Han Dynasty around 206 BC to 220 AD. They found that the magnetic properties of lodestone aligned the needle towards the Earth's magnetic north pole.

You would have a compass that pointed north, but a lot of the explorers compasses froze up
A compass
A compass is the instrument that always shows magnetic North. A compass is used to show which way you are traveling.
Around the thirteenth century, this magnetic compass became important to mariners because sometimes, their astronomical cues would be hidden by the clouds and they couldn't find direction but with this compass, it always pointed north to the earth's magnetic field and revealed all the directions.

the compass would point north because it Always points north unless you are at the north pole. :)
The point to which a compass always points is the magnetic North Pole. This is because the compass needle aligns itself with the Earth's magnetic field, which is directed towards the magnetic North Pole.
If you point the north side of the compass away from you the compass will point south. Because the needle always points north (magnetism).
