**Magnetic Field Analysis**

You may want to review [Page 796](#). For help with math skills, you may want to review:

- [The Vector Cross Product 1](#)
- [The Vector Cross Product 2](#)

**Figure Analysis**

The only figure shown illustrates a circular arc with a current \( I \) flowing through it. The arc spans from radius \( r_1 = 0.9 \, \text{cm} \) to \( r_2 = 1.8 \, \text{cm} \), with a point \( P \) situated at the center of curvature of the arc.

**Exercises**

**Part A:**

*Problem:*
What is the strength of the magnetic field at point \( P \) in the figure? Assume that \( I = 4.6 \, \text{A} \).

*Solution:*
Express your answer to two significant figures and include the appropriate units.

*Input Section:*
\[ B = \text{Value} \, \text{Units} \]

*Action:*
Submit your answer.

**Part B:**

*Problem:*
What is the direction of the magnetic field at point \( P \) in the figure?

- \(\circ\) into the screen  
- \(\circ\) out of the screen

*Action:*
Submit your answer. Confirmation will be shown if correct.
