squeezing a field

I'm designing a small PCB with essentially 5 sync buck switchingregulators. Board space is tight so I want to put the inductors on thebottom of the multilayer board. There's a 0.2" gap between the bottomof the board and a big aluminum flange.Unshielded drum cores have the most energy storage per volume ordollars. They store energy in the universe instead of in ferrite. Goodcooling too.Something like this just fits mag field lines will bounce off the PCB planes and the flange,change from the classic bar magnet pattern into a pancake . I wonderwhat that will do to its electrical behavior.

If you don't have it, I can recommend buying the Bode 100 analyzer. It's not terrible expensive, and the SW is great.

They stopped making G3s a few years before Apple announced moving to Intel CPUs. It's 32-bit power-pc based, I don't where you'd find a

32-bit PPC linux these days. The last Debian to support 32-bit PPC was version 8 "Stretch" for which support ended in 2020.
