**Educational Content: Magnetic Potential Energy and Magnetic Torque of a Coil**

---

**Problem Statement:**

The coil in the figure carries current \( i = 1.83 \text{ A} \) in the direction indicated, is parallel to an xz-plane, has 4 turns and an area of \( 5.89 \times 10^{-3} \text{ m}^2 \), and lies in a uniform magnetic field \(\vec{B} = (1.73 \hat{i} - 2.49 \hat{j} - 3.73 \hat{k}) \text{ mT} \).

**Questions:**
(a) What is the magnetic potential energy of the coil-magnetic field system?
(b) What is the magnetic torque (in unit-vector notation) on the coil?

---

**Solution:**

(a) **Magnetic Potential Energy Calculation:**

- **Number:** -1.07E-4 
- **Unit:** \(\mu\text{J}\)

(b) **Magnetic Torque Calculation:**

- \(\hat{i}\) component: 3.89E-3
- \(\hat{j}\) component: 0
- \(\hat{k}\) component: 8.14E-5 
- **Unit:** \(\mu\text{N} \cdot \text{m}\)

---

**Explanation of Diagram:**

The image features a coil positioned parallel to an xz-plane with current \( i \) flowing in the direction indicated by an arrow. The magnetic field \(\vec{B}\) is denoted by the components \(1.73 \hat{i} - 2.49 \hat{j} - 3.73 \hat{k} \text{ mT} \). The arrows on the diagram represent both the direction of the current in the coil and the direction of the coordinate axes (x, y, z).

- **Figure Key Elements:**
  - A circular coil laying in the xz-plane.
  - Coordinate system \((x, y, z)\) illustrated for spatial orientation.
  - Arrow indicating the direction of electric current \(i\).

---

This problem encompasses the principles of electromagnetism, involving concepts such as magnetic potential energy and magnetic torque in a uniform magnetic field.
