Question
**Interactive Exercise on Magnetic Fields**

**Scenario:**
The two insulated wires shown in the figure cross at a \(30^\circ\) angle but do not make electrical contact. Each wire carries a current of 5.0 A. Points 1 and 2 are located 3.5 cm from the intersection, equidistant from both wires.

**Question:**

**Part A:**
What is the magnetic field at point 1?

- **Instructions:** Express your answer in microteslas. Enter your answer as positive if the magnetic field is directed into the page and as negative if the magnetic field is directed out of the page.

  - **Input Box:** 
    \[
    B_1 = \quad \boxed{}\ \mu T

**Diagram:**

**Figure Description:**
- The figure illustrates two crossing wires carrying a current of 5.0 A each.
- The wires cross at an angle of \(30^\circ\).
- Points 1 and 2 are marked, each positioned 3.5 cm from the intersection and equidistant from both wires.

Participants can calculate the magnetic field at each point using these details and the magnetic field formula for a long straight conductor:

\[
B = \frac{\mu_0 I}{2\pi r}
\]

Where:
- \(B\) is the magnetic field,
- \(\mu_0\) is the permeability of free space,
- \(I\) is the current,
- \(r\) is the distance from the wire.
