In what direction does a compass needle point?

In summary, a compass needle can point in different directions depending on its location and the presence of a bar magnet. It can point towards the magnetic field lines, the north or south magnetic pole, or approximately towards the north or south in different hemispheres. It is important to consider the relationship between geographical and magnetic directions when using a compass.

A hint is that the geographical north (above Canada) is the magnetic south.
The geographical south (Antarctica) is the magnetic north.

Makes sense. Thank You.
 

What is a compass needle?

A compass needle is a small magnet that is able to rotate freely on a pivot. It is used to determine the direction of magnetic north, which can help determine one's orientation and navigate when traveling.

How does a compass needle work?

A compass needle works by aligning itself with Earth's magnetic field. This field is generated by the Earth's core and extends outwards, creating a north and south pole. The north end of the compass needle will always point towards Earth's magnetic north pole.

Why does a compass needle point north?

A compass needle points north because it is attracted to Earth's magnetic north pole. This is due to the fact that opposite poles of a magnet attract each other.

Can a compass needle point in any other direction?

Yes, a compass needle can point in any direction as long as it is not affected by external magnetic forces. If the compass needle is near a strong magnet or metal object, it may not point towards magnetic north accurately.

Does a compass needle always point in the same direction?

No, a compass needle may not always point in the same direction. Earth's magnetic field is not constant and can change over time. This means that the direction of magnetic north can also change, causing the compass needle to point in a different direction.
