[Lowfer] Ferrite Loading Coil ?

[Pete Cranwell]

I guess what I'm trying to say is that unless there is current flow in the
coil you cant generate any flux.  Current flow is determined by applied
voltage and complex impedance (wire losses, core losses etc).  Have I missed
something?  Isn't magnet flux generated when electrons move through a wire &
EMF is generated when magnet flux cuts a wire ?

Cheers

Pete

Bmax = Epk X 10^2 / 4.44 x Ae x N x f

Epk = peak rms voltage
Ae = cross sectional area in cm^2
N = number of turns
f = frequency in MHz
