1. Two wires running parallel to each other in a circuit can provide an inductance that is adjustable with their length. For the loop shown below with length L=2m , width w=5cm , and wire radius a=1mm , find the inductance in H? 2. Relevant equations 3. I thought i could find the inductance by using the equation mu0/pi(L*ln((w-r)/r) + w*ln((L-r)/r) and i found 3.3*10^-6 but it don't seem good. Could you help me?
