A square loop of wire, with sides of length $L$, carries a current $I$. Show that the magnetic field at the center of the square is $B = frac{2sqrt{2}mu_0 I}{pi L}$

Step 1
To find the magnetic field at the center of one side of the square loop, we can use the Biot-Savart law. The Biot-Savart law states that the magnetic field at a point due to a current-carrying wire is directly proportional to the current and inversely proportional Show more…

A square loop of wire of edge length $a$ carries current $i$. Using the results of Problem 11 , show that, at the center of the loop, the magnitude of the magnetic field produced by the current is $$ B=\frac{2 \sqrt{2} \mu_{0}|i|}{\pi a} $$.
A wire is formed into the shape of a square of edge length $L(\text { Fig. } \mathrm{P} 30.67)$ . Show that when the current in the loop is $I,$ the magnetic field at point $P,$ a distance $x$ from the center of the square along its axis is $$B=\frac{\mu_{0} I L^{2}}{2 \pi\left(x^{2}+L^{2} / 4\right) \sqrt{x^{2}+L^{2} / 2}}$$
A wire is formed into a square of edge length $L$ (Fig. P30.69). Show that when the current in the loop is $I$. the magnetic field at point $P$, a distance $x$ from the center of the square along its axis, is $$ B=\frac{\mu_{0} I L^{2}}{2 \pi\left(x^{2}+L^{2} / 4\right) \sqrt{x^{2}+L^{2} / 2}} $$
