SUMMARY
The formula for calculating the magnetic field due to a finite wire carrying current is given by the equation b = (μ₀ I L) / (4πr), where L is determined by the dimensions of the wire and r is the distance from the wire to the point of interest. In this discussion, a rectangular loop measuring 4.20 cm by 9.50 cm generates a magnetic field of magnitude 3.60×10-5T at its center, directed away from the observer. The values used in the equation include a = 0.042 m and b = 0.095 m, which are essential for calculating the magnetic field accurately.
