Question

The figure shows a cross section of two parallel wires I1 = 11 A out of the paper and I2 = 8.2 A into the paper. If the distance R = 6.0 mm, what is the magnitude and direction of magnetic field at position P?

The diagram represents a linear arrangement of two current elements \( I_1 \) and \( I_2 \) along with points P and X in an electric circuit. Here is the transcribed explanation of the diagram to appear on an educational website:

---

### Diagram Explanation:

**Description:**

1. **Current Elements:**
   - There are two current elements, denoted as \( I_1 \) and \( I_2 \). These are shown as circular objects with current directions (indicated by the symbols inside the circles: a dot for \( I_1 \) and a cross for \( I_2 \)). The dot usually indicates current coming out of the plane, and the cross indicates current going into the plane.

2. **Connection:**
   - Both current elements are connected in a linear fashion along a straight line.
   - A resistor \( R \) is placed between \( I_1 \) and \( I_2 \), and another resistor \( R \) is placed between \( I_2 \) and point P.

3. **Points and Notations:**
   - \( I_1 \): The first current element at the leftmost position.
   - \( I_2 \): The second current element, positioned to the right of \( I_1 \).
   - P: A point further to the right of \( I_2 \).
   - X: A point located at the junction between \( I_1 \) and \( I_2 \).

**Explanation:**
This arrangement might represent a part of an electric circuit under study, where the focus is on analyzing the behavior of current and potential differences across the elements. The resistors \( R \) indicate the presence of opposition to current flow between the current elements and the points indicated. 

Understanding such diagrams is crucial for comprehending the principles of electric circuits, including concepts like series and parallel connections, Kirchhoff's laws, and the principles of superposition in electric networks.
