Home / Examples / Magnetic Analysis (Gauss, Static Analysis/Harmonic analysis) / Example 9: Inductance of Loop Coil
The inductance of a loop coil is solved.
The vectors of the magnetic field and the magnetic flux density are also solved.
Unless specified in the list below, the default conditions will be applied.
Results will vary depending on Femtet version and the PC environment.
