A square-shaped wire loop of side L is carrying a current I. What is the magnetic field at the point of intersection of diagonals of the square wire loop?
(2√2 μ0I) / (πL)
The magnetic field at the center of a square loop carrying current I can be found using the Biot-Savart law. The contribution from each side is considered, and the superposition principle is applied. The derived formula for the net magnetic field at the intersection of diagonals is:
B = (2√2 μ0I) / (πL).
Thus, the correct answer is option (b).
