I have some circular ferrite bobbins with a hole down the centre.
I'v seen these commercially installed with a steel bolt down the centre, is this going to significantly affect the bh curve or saturation point?, this example has a 10mm winding diameter and a 4mm bolt, so the bolt diameter is significant.
In professional speaker cabs crossover chokes always had nylon bolts holding them down.
