Answer 2

Answer:

Hang the bar magnet with the string, it will always rest in North-South direction.

Explanation:

If you hang a bar magnet with a string and suspend it down, it will always rest pointing its north to the North direction.  The main reason behind this phenomenon is the Earth's core.  

The north pole of a magnet almost points north while on free suspension as it lines up to the Earth's magnetic core. This is the reason for its application in compass.
