can anyone pls give a right answer​

Answer 1

Answer:

When iron nails are brought near one end of a magnet, the nearer end of piece acquires an opposite polarity by magnetic induction. Since unlike poles attract each other, therefore, iron nails are attracted towards the end of the magnet. Thus, the iron nail first becomes a magnet by induction and then it is attracted.

Explanation:

The mechanism behind the attraction of iron nails by a magnet is the magnetic effect. According to this effect, the magnet attracts a metal (here iron nails).
