I used three methods to calculate the coil inductance value but got three different values, 1. Directly extract the coil inductance, namely mf, LCiol_1, 2. The ratio of the volumetric magnetic energy density to the square of the current is fffmf.Wmav/i^2, 3. The ratio of magnetic energy to the square of current is mf.intWm/i^2 In theory, the coil inductance value is fixed, and the inductance can be calculated in the above three methods, why the coil inductance obtained is different? I am confused, which method should be used to obtain the value, please advise me, I am grateful!
