प्रश्न
Explain the mechanism of attraction of iron nails by a magnet when brought near them.
Advertisements
उत्तर
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.
