Question 1.

A bar magnet has no markings to indicate its poles. How would you find out near which end its North pole is located without using another magnet ? Class 6

Answer:

We can determine poles by suspending it freely.

A freely suspended magnet comes to rest along the north-south direction. The end of the magnet that points towards north direction is called the North pole of the magnet. The other end that points towards the South direction is called the South pole of the magnet.

Question 2.

If the earth is itself a magnet, can you guess the poles of earth’s magnet by looking at the direction of the magnetic compass? Class 6

Answer:

1. A magnetic compass aligns itself with Earth’s magnetic field. The needle of a compass points towards the magnetic North pole of the Earth.
2. When you hold a compass horizontally, the end of the needle that points towards the geographic north actually points the magnetic North pole.
