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 magnetic field lines

Options

A. intersect at right angles to one another
B. intersect at right angle of `45^(@)` to one another
C. do not cross one another
D. cross at an angle of `60^(@)` to one another

Explanation

**Step-by-Step Solution:**

1. **Understanding Magnetic Field Lines:**
- Magnetic field lines are visual representations of the magnetic field around a magnet. They indicate the direction and strength of the magnetic field.

2. **Direction of Magnetic Field Lines:**
- Magnetic field lines always start from the North Pole of a magnet and end at the South Pole. This means that outside the magnet, the lines flow from North to South.

3. **Behavior of Magnetic Field Lines:**
- The lines do not intersect each other. If they did, it would imply that at the point of intersection, the magnetic field has two different directions, which is not possible.

4. **Spacing of Magnetic Field Lines:**
- Near the poles of the magnet, the magnetic field lines are closer together, indicating a stronger magnetic field. Conversely, they are more widely spaced out in areas away from the poles, indicating a weaker magnetic field.

5. **Conclusion:**
- Based on the properties of magnetic field lines, the correct statement is that they do not cross each other. Therefore, the answer to the question regarding the behavior of magnetic field lines is that they do not intersect.

**Final Answer:**
- The correct option is that magnetic field lines do not cross each other.
