The image above presents a conceptual problem involving a coil and a magnetic field, suitable for educational purposes. Here's a detailed transcription and explanation:

### Problem Statement:
A coil is illustrated with the following characteristics:
- It carries a current \( i = 1.77 \, \text{A} \).
- The coil is parallel to an xz plane.
- It has 4 turns.
- The coil's area is \( 5.95 \times 10^{-3} \, \text{m}^2 \).
- It is placed in a uniform magnetic field given by \( \mathbf{B} = (1.93 \, \hat{i} - 2.33 \, \hat{j} - 3.46 \, \hat{k}) \, \text{mT} \).

### Questions:
(a) Calculate the magnetic potential energy of the coil-magnetic field system.

(b) Determine the magnetic torque on the coil, expressed in unit-vector notation.

### Diagram Explanation:
The diagram features a coil aligned along the xz plane, with axes labeled \( x \), \( y \), and \( z \). The current \( i \) flows through the coil in the direction indicated. The diagram provides a visual aid for understanding the spatial orientation of the coil relative to the magnetic field.

### Inputs for Answers:
- **(a) Box for Number**: Input the calculated magnetic potential energy.
- **Unit**: Select the appropriate unit for potential energy.
- **(b) Boxes for Number**: Input the components of the magnetic torque vector in terms of \( \hat{i} \), \( \hat{j} \), and \( \hat{k} \).
- **Unit**: Choose the correct unit for torque. 

This setup encourages students to apply concepts from electromagnetism, linking theoretical calculations with visual interpretation.
