उत्तर
To find the north-south direction with a magnet:
- Float a bar magnet or magnetized needle on water using a leaf or cork.
- Let it settle; it will align with Earth's magnetic field.
- One end points north, the other south.
Verify using sunrise (east) and sunset (west). Now you have found the north-south direction at that place!
