### Problem: Magnetic Field Calculation#### Item 4**Part A**Find \( B \) at the center of the 4.1 cm-radius semicircle in the figure (Figure 1). The straight wires extend a great distance outward to the left and carry a current \( I = 5.7 \) A.Express your answer using two significant figures.\[ B = \_\_\_\_\_\_ \text{ T} \]Submit Request AnswerProvide Feedback---#### Figure ExplanationThe figure below shows a straight segment of wire carrying a current \( I \). The wire then forms a semicircle with a radius of 4.1 cm before continuing straight again in the opposite direction of the initial segment.[Figure](Key: Current direction is indicated by arrows along the wire.)---#### Notes:1. The magnetic field \( B \) at the center of the semicircle can be found using the Biot-Savart law.2. The contribution of straight wires needs to be considered separately if within the regions of interest due to significant distance.3. Ensure to use appropriate significant figures and units for the final answer.

We will first write expressions for magnetic fields, due to infinite current carrying wire, and due…
