Hello sir
I am working on fluxgate sensors. The basic fluxgate principle is that the ferromagnetic core is excited by the ac current ( Iexc) of frequency f into the excitation winding. The core permeability mu(t) is therefore changing with 2f frequency. If the measured dc feild B0 is present, the associated core flux is also changing with 2f and voltage (Vind) is induced in the pickup(measuring) coil having N turns.

So according to this my questions
Q1) How to drive the material into saturation?

Q2) How can i measure the induced emf from the secondary coil?

Q3) Final thing to create external magnetic field should i need to use mfnc or mf?

Thanks in advance.
