Question
The problem involves finding the magnetic field (both its magnitude and direction) at the center, labeled as point C, of a rectangular loop of wire. The accompanying figure illustrates a rectangular loop with dimensions: length \(a\) is the longer side, and width \(b\) is the shorter side. Current \(I\) flows through the loop, as indicated by arrows on the wire segments.

**Detailed Explanation of Diagram:**

- The loop is rectangular, with horizontal sides measuring \(a\) and vertical sides measuring \(b\).
- The current \(I\) flows clockwise around the loop, as shown by the red arrows along the sides.
- The center of the loop is marked by a dot labeled "C."
- Arrows near the sides of the rectangle indicate the path and direction of the current.

To find the magnetic field at point C, one would typically apply principles from electromagnetism, such as the Biot-Savart Law or Ampère's Law, considering the symmetry and geometry of the problem.
