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?

$\frac{μ_οI}{π L\sqrt{2}}$ $\frac{2\sqrt{2}μ_οI}{π L}$ $\frac{2μ_οI}{π L}$ $\frac{\sqrt{2}μ_οI}{π L}$

$\frac{2\sqrt{2}μ_οI}{π L}$

The correct answer is Option (2) → $\frac{2\sqrt{2}μ_οI}{π L}$
