Charles,
Thanks for the info. The parallel core flux gate design (my name for it)
consists of two cores such as a rod or wire or strip of metglas. Each cor=
e
has a excitation winding. The two coils are placed in parallel inside a
overall sense winding. The excitation currents in the two coils are
arranged to produce cancelling flux in the sense coil. The signal from th=
e
sense winding is processed as usual.
