Calculators of inductance - this page collates several interactive calculators of inductance for various circuits: straight conductor, loop, coil, etc. as listed in the table below.
The specific analytical equations are listed in each of the calculators separately, with several of them based on the Grover's1) and Paul's books,2) as well as other sources (specified in each calculator).
