A positive charge is moving towards a person. The direction of magnet...
**Explanation:**
When a positive charge moves in a magnetic field, it experiences a force perpendicular to both its velocity and the magnetic field direction. This force is given by the formula:
**F = q(v x B)**
Where:
- **F** is the force experienced by the charge
- **q** is the charge of the particle
- **v** is the velocity of the particle
- **B** is the magnetic field
In this case, the positive charge is moving towards a person, so its velocity is directed towards the person. The force experienced by the charge will be perpendicular to both the velocity and the magnetic field.
If the magnetic field lines were vertically upward or downward, the force experienced by the charge would be in the horizontal direction. This would cause the charge to move in a circular path around the person.
However, if the magnetic field lines were directed in a clockwise or anticlockwise direction, the force experienced by the charge would have a vertical component. This means that the charge would be pushed either upwards or downwards, depending on the direction of the magnetic field.
Since the positive charge is moving towards the person, the force experienced by the charge must be directed away from the person in order to push the charge towards them. This can only happen if the magnetic field lines are directed in the **anticlockwise** direction, as shown in the diagram below:
```
X → O

O ← X
```
Here, the X represents the positive charge, the O represents the person, and the arrows represent the direction of the magnetic field lines.
Therefore, the correct answer is option **B) Anticlockwise direction**.
