PASSAGE-I : A magnetic field is described by drawing the magnetic field lines. The magnetic field lines always begin from the north pole of magnet and end on the soth pole of the magnet. They do not intersect each other. They come closer to one another near the poles but they are widely separated at other places.
The strength of magnetic field is weak at

Options

A. north pole
B. south pole
C. centre
D. both of the poles

Explanation

### Step-by-Step Solution:

1. **Understanding Magnetic Field Lines**:
- Magnetic field lines are visual representations of the magnetic field around a magnet. They always originate from the north pole and terminate at the south pole.

2. **Characteristics of Magnetic Field Lines**:
- The lines never intersect each other, indicating that at any point in space, the magnetic field has a unique direction.
- The density of these lines indicates the strength of the magnetic field; closer lines mean a stronger field, while widely spaced lines indicate a weaker field.

3. **Strength of Magnetic Field Near the Poles**:
- Near the poles of a magnet, the magnetic field lines are closer together, which means the strength of the magnetic field is maximum at the poles.

4. **Strength of Magnetic Field at the Center**:
- In contrast, at the center of the magnet, the magnetic field lines are more widely spaced, indicating that the strength of the magnetic field is weaker compared to the poles.

5. **Conclusion**:
- Therefore, the strength of the magnetic field is weak at the center of the magnet.

### Final Answer:
The strength of the magnetic field is weak at the **center** of the magnet.
