Q 1 (25 Points)
Consider the current-carrying loop formed of radial lines and segments of circles whose centers are at point P as shown below.
Find the magnetic field B (magnitude and direction) at P using Biot-Savart Law below.
\[
\overrightarrow{\mathbf{B}}=\frac{\mu_{0} I}{4 \pi} \int \frac{d \overrightarrow{\mathbf{S}} \times \hat{\mathbf{r}}}{r^{2}}
\]
