Hi all, I am trying to get my head around some experiment results but I am struggling a bit.
According to my notes H field strength is equal to MMF / effective length
However this doesn't take into account the effects of reluctance? Eg a toroid made from 2m of iron bar and a straight 1m length of iron bar will require the same mmf to generate the same H field regardless that in one case 50% of the path is through the low permitivitty of air?
can anyone shed some light on this for me please
thanks in advance guys and girls
