Question

If a bar magnet is broken into two pieces as shown in the figure below, what can you incur or observe from this experiment?​

• A. Each part is found to have a single pole (north pole) in a magnet.
• B. Each part is found to have its own north and south pole in a magnet.
• C. Each part is found to have a single pole (south pole) in a magnet.
• D. Can’t be determined.

Answer 1

The correct option is B Each part is found to have its own north and south pole in a magnet.

If a bar magnet is broken into two pieces, it is observed that the two pieces of the magnet act as an independent magnet with its own north and south poles. If each piece of the magnet is again broken into smaller pieces, it observed that a magnet behaves like an independent magnet. It is not possible to isolate one pole from a magnet, i.e the north and south poles cannot exist separately. It can be concluded that in a magnet a single pole can never exist or the poles always exist in pairs.
