Answer 1

Explanation:

Step 1

Wake up early in the morning when the sun is rising.

Step 2

We know that the sun rises in the east.

So now we know where east is.

Step 3

Now hang the bar magnet on a string attached to it's center and make sure that the magnet can move freely.

Step 4

Now when the magnet will come to a stop and will become still, stand facing the sun.

Step 5

Now point your hand towards the left direction. You have found the north direction.

Now just mark the end of the bar magnet facing north and 'N'.
