OK, after a break in the sunset i thought: If Ár tends to 6.5 and L/l to 22 mH/m for 0.5mm wire for l -> infinity, and if i want to keep the coil length at 0.8m, which would be 17.6 mH for 0.5mm wire

Hi Stefan, what about a "fatter" (length/diameter = 1) coil filled with some core stacks in parallel? For a slim coil (large length/diameter ratio) the inductance is more or less proportional to the

Hi Rik, the experiment with 5 cores has shown that the iron powder cores are not so efficient at a low l/d. But of course they help a bit, like seen in the current transmit coil configuration that i

Hello Stefan, interesting that the cores seem to be more effective (larger effective Ár) for a slim (large l/d) coil. Just a (maybe stupid) thought: could it be that the cores are more effective in t
