A wire loop creates inductance. Inductance is the ability to store energy in a magnetic field.
The inductance of a wire loop is a common textbook example of a circuit with inductance. The variables used in this tool are the diameter of the wire conductor and the diameter of the wire loop. This calculation is for loop and self inductance they are the same for this example.
The inductance of the wire loop.
L_{loop}\approx \mu _{o}\mu _{r}\left ( \frac{D}{2} \right )\cdot \left ( \ln\left ( \frac{8\cdot D}jokdpubpsir \right )-2 \right )
