Magnetic strength of the magnet is concentrated at both the poles of the magnet.
Magnetic strength refers to the ability of a magnet to attract or repel other magnetic materials. In a magnet, the magnetic strength is not evenly distributed throughout the entire magnet. Instead, it is concentrated at the poles of the magnet. Let's understand this in detail:
1. Magnetic Poles:
- A magnet has two poles - the North Pole (N) and the South Pole (S).
- These poles are the regions where the magnetic strength is the highest.
- The North Pole of one magnet attracts the South Pole of another magnet, and vice versa.
- Like poles (N-N or S-S) repel each other, while unlike poles (N-S) attract each other.
2. Magnetic Field Lines:
- Magnetic field lines are imaginary lines that represent the magnetic field around a magnet.
- These lines emerge from the North Pole and enter the South Pole.
- The density of these lines indicates the strength of the magnetic field.
- The lines are closer together near the poles, indicating a higher concentration of magnetic strength.
3. Magnetic Flux:
- The magnetic strength of a magnet is measured by its magnetic flux.
- Magnetic flux is the total number of magnetic field lines passing through a given area.
- The magnetic flux is higher near the poles, indicating a higher concentration of magnetic strength.
4. Experiment with Iron Filings:
- If you place a bar magnet on a piece of paper and sprinkle iron filings around it, you will see a pattern forming.
- The iron filings align themselves along the magnetic field lines, giving a visual representation of the magnetic strength.
- The pattern formed by the iron filings shows that the magnetic strength is concentrated at both the poles of the magnet.
Therefore, the correct answer is option 'B' - the magnetic strength of the magnet is concentrated at both the poles of the magnet.
