Rectangular Frame Magnetic Field Calculator | Biot-Savart Law Calculation

The model is represented as a rectangular current loop, where the current element is modeled as an infinitesimal straight line segment. The magnetic field is computed using the Biot–Savart–Laplace law. The calculation is reduced to single integrals, which have analytical solutions. As a result, the final expressions are given in terms of elementary functions.
