Question 4

North pole of a magnet can be identified by

(a) Another magnet having its poles marked as North pole and South pole.

(b) Another magnet no matter whether the poles are marked or not.

(c) Using an iron bar.

(d) Using iron filings.

Answer 1

Option (a) is the correct answer.

The north pole of the unmarked magnet can be identified only if we have another magnet having its pole marked as North and South pole because only then we can see the attraction and repulsion between North-South poles and North-North poles respectively.
