SUMMARY
AC windings and DC windings serve distinct purposes in electrical applications. AC windings are designed to operate with alternating current, while DC windings are utilized for direct current applications. In the context of fluxgate magnetometers, a DC winding is employed to bias the current on an AC transformer, effectively canceling out the imposed DC magnetic field. This technique ensures accurate measurement of DC magnetic fields by nullifying the output signal.

A standard fluxgate magnetometer for measuring dc magnetic fields uses a dc winding (biasing current) on an ac transformer to cancel the imposed dc magnetic field and null the output signal. Sometimes the dc bias current is imposed directly on the ac secondary output coil, as shown in the thumbnail.
