Isolated magnetic poles do not exist'. explain?
A. 1. If a bar magnet is cut into smaller and smaller pieces eventually ending with the smallest possible piece, this smallest piece also behaves as a magnet with its two poles N and S.
2. So, North & South poles in a magnet exist together in pair.
3. Thus isolated magnetic poles do not exist.
Explain irreversible process A process which takes the system to the non equilibrium state is known as irreversible process. *It can't be retraced in the reverse direction.
Production of a magnet: Magnets can be produced in a variety of ways, generally the method used is determined by the type of magnet required. Using the stroke method
