Title: Understanding the Magnetic Force on Stationary Charges

---

**Question:**

A stationary positive charge \(+Q\) is located in a magnetic field \(B\), which is directed toward the right as indicated. The direction of the magnetic force on \(Q\) is:

**Options:**
1. Down.
2. There is no magnetic force.
3. Up.
4. Toward the right.

---

**Diagram Explanation:**

The diagram illustrates a stationary positive charge labeled \(+Q\) within a magnetic field. The magnetic field lines are shown as horizontal arrows pointing to the right. The charge \(+Q\) is positioned within these lines, indicating its presence in the magnetic field.

---

**Concept Review:**

In physics, the magnetic force on a charge is determined by the charge's motion in the magnetic field. According to the Lorentz force law, the magnetic force on a stationary charge is zero because it relies on the velocity of the charge. Thus, for a stationary charge in a magnetic field, no magnetic force is exerted.

**Answer Explanation:**

This scenario represents a key principle: a stationary charged particle does not experience a magnetic force. Therefore, the correct answer is:

2. There is no magnetic force.
