WebFor two parallel wires whose length lis great compared to their distance dapart, (Figure 2) the inductance of the loop is [2, pp. 39]: L l d R d l =+−o µ π ln 1 4 [3] For l= 0.5 meter and a wire-wire spacing d= 1 cm, results are: L= 0.505 µH for 14 gauge; L= 0.551 µH for 16 gauge and L= 0.598 µH for 18 gauge. WebFind out the self-inductance of the coil. Answer- When we apply the above equation for inductance, we see that we have got our Φ as 300 mWb which equals 0.3 Wb. Further, the N is 1000 and I is 8 A. L = ΦN/I. L = (0.3 Wb) (1000)/8A. L = 37.5 H. Therefore, the coil’s self-inductance is 37.5 H. Physics Formulas.
