To solve the problem, let's analyze the situation in detail.
### Step-by-Step Solution:
1. Understand the Properties of a Bar Magnet:
A bar magnet has two poles: a north pole and a south pole. When unbroken, it has a magnetic field flowing from the north pole to the south pole.
2. Cutting the Magnet:
Suppose you decide to cut this bar magnet into 10 equal pieces.
3. Magnetic Properties of Pieces:
When you cut a bar magnet into smaller pieces, each piece will still retain its magnetic properties. Each piece will develop its own north and south poles. This is a fundamental characteristic of magnets; even the smallest piece will always have a north pole and a south pole.
4. Determination of Number of Magnets:
Since we cut the original bar magnet into 10 equal pieces and each piece will become an individual magnet with its own north and south pole, you will end up with 10 individual magnets.
### Conclusion:
So, if you cut a single bar magnet into 10 equal pieces, you will end up with 10 individual magnets, each having its own north and south pole.
Therefore, the correct answer is:
10 individual magnets, each with a north and south pole.
