Mention two points which Ravi would have kept in mind while moving the magnet along the length of the iron nail to make the observation as stated above.

Answer:
The phenomenon of a magnetic substance acquiring magnetism due to the presence of a magnetic material around it is known as magnetism. When a bar magnet is brought near an iron nail, the iron nail gets magnetised. When a bar magnet is brought near an iron nail the polarity developed at the farthest end of the nail is the same as the polarity of the tip magnet with which it is in contact.
