Greetings

I am trying to confirm some basic quantities, before design more complicated topologies, in Maxwell 3D. So, I begun with the inductance of a simple coil, as shown below

OK, apparently I was wrong on how inductance is calculated for such a short coil.nBy using Wheeler's approximation formulanL = 30.534 μH, pretty close to simulation results (with 2% error)nI attach Wheelers' paper (which is nearly 100 years old)nArrayn

sorry for being late. you already realized the scale of the problem with coils... luckily it is not microwave.nn
