  • The diagram shows a two-dimensional coordinate system with labeled axes for \(x\), \(y\), and \(z\) directions.
  • An elliptical loop is drawn on the plane defined by the \(x\) and \(y\) axes.
  • A current, denoted by \(I\), is indicated flowing through the loop, following the direction of the loop path.
  • Within the area enclosed by the loop, several vertical arrows point in the positive \(z\) direction, representing the magnetic field vector \(\vec{B}\).
  • The diagram also labels a differential length element, \(d\text{l}\), along the edge of the loop, suggesting the integral nature of the calculation.
